How would you prepare 1 liter of a 300 mM NaCl solution?
1.You would first get the molar mass of NaCl. NaCl: 58.443 g/mol 2. 300mM=0.300Mol/litre so 0.300*58.443=17.5329g so you take a litre of distilled water and add that amount of salt.
What is the difference between a marble countertop, and a granite countertop?
AnswerTypically the granite that is used for a floor is in tile form. Example, 12" x 12" granite floor tiles. However, granite is available in many sizes and shapes as well as thickness. Floor tiles made from granite are usually available in 3/8" for smaller sizes and 1/2" for the larger sizes. When using granite for countertops, the most common thickness would be 3 cm or 1-1/4" thick granite slabs. The average size of a granite slab is 68" x 113". A granite fabricator will custom cut the slab and polish the edges. The thickness. Floor tile are 3/8 to 1/2 inch thick and counter top is 3/4 to 1 inch with the edge usually double thick.www.a4architect.comHow to choose floor finishes.There are many different types of floor finishes available for a home owner to choose from.1.Wood laminates Floor Boards.These are floor finishes made of HDF[High Density Fibre] and look like wood strips.They are made from wood fibres that have ben highly compressed making it harder than the more common MDF Fibre boards.They come in various natural wood vineers such as peach,oak or mahogany. The strips are joint together by grooves and are laid ontop of an underlay which is laid on the concrete ground surface.They are easy to fix by care should be taken to leave expansion joints at the edges to cater for expansion in hot weather.Failure to this, the floor boards will warp upwards and dislocate frm the grooves.They come in various thicknesses usually from 8m to 16mm and are used dependng on the human traffic envisaged. The thicker they are, the more durable they will be. They should be avoided in wet areas.They are relatively low cost.2.Natural wood Floor finishes.Parquet floor finish.This consists of solid hardwood blocks fixed with an adhesive on the floor surface and arranged to form a pattetn-the herringbone patern is very common with this finish. The wooden blocks can be of varous sizes and thicknesses.Wood strips.These are hardwood strips joined together to form a floor finish on the floor. This kind of flooring is simple and takes less time to fix. The strips are laid in random length.3.Ceramic tiles.This type of floor finish is very common due to its durability and affordability and choice of design.Ceramic tiles are the number one choice for wet areas such as kitchens and bathrooms due to its water-proofing capabilities.Ceramic tiles also come in various sizes, patterns, colours and shapes.Ceramic tiles are made from clay which is mined form the ground. The clay is crushed and dry-pressed when in a wet stage to form the shape using a pneumatic punching press. The tile is then dried and a glaze is applied ontop. Glazing is the application of fine glass powder to the surface. The tile is then fired whereby the glaze particles melt into each other to produce a granite-like sueface.Italy is one of the world's largest producers of ceramic tiles.Ceramic tiles are easy to clean.Ceramic tiles are also easy to fix. They are stuck onto the surface usung cement motar in a ratio of 1:3 and hand-placed and positioned usung plastic spacers to create an evenness. There is a special cermic tile cutter that is used to cut the tiles into shape.Ceramic tiles vary in pricing depending on the quality,colour and pattern.They are relatively low cost.4.Granito tiles.These are Porcelain ceramic tiles and are more durable and can be used in the out-door. They are made from porcelain granules and are fired at much higher temperatures than ceramic tiles.They are comon in sizes 450mm by 450mm up to size 600mm by 600mm.They come in variopus colours and textures and are very aesthetically appealing and long lasting.They are mainly used in corporate offices, banking halls, large shopping malls e.t.c since their large sizes[600mmby 600mm ] can keep up with the large floor scales associated with commercial buildings and can also handle high human traffic in durability.They are slightly more expensive than ceramic tiles.5.Granite Tiles.The word 'granite' is derived from the Latin word 'Granum ' meaning the granles that characterise the texture and appearance of granite.Granite is an igneus rock that is mined from the ground and cut and polished to the required tile sizes.Granite as a floor finish is very aesthetically appealing due to its natural look. Its also expensive compared to other manufactured finishes such as ceramics.Its very long lasting. It comes in sizes of 1.2m by 2.4 m which can be cut into smaller size tiles as desired. Its also commonly used to make kitchen top surfaces.6.Marble.This is a metamorphic rock made from the joining of clacite[limestone] rock at high temperatures and pressure. This destroys any sign of fossils and sedimentary structure in the rocks to create characteristic swirls and veins from the impuritties such as clay ,silt and iron oxides.Marble comes in various colour shades according to the region that it is mined from.It is mined,polished and cut to the desired sizes. Its available in slab sizes of 1.2meters by 2.4 meters .This is a very beautiful floor finish and very expensive. Since its very expensive to finish complte floor areas with marble, its usually placed in spacific areas such as the entrance foyer where its most visible.7.Terrazzo floor finishThis finish is desirable where ther eis high traffic due to its durablility. Its also water prof so it can be used in wet areas and its easy to clean. It can also be laid on the out doors.Once the concrete floor is laid, a 1 inch hick layer of concrete is laid then patterns are created using plastic dividing strips embedded ontop of the wet concrete surface. A final layer of marbel-chips of various colours is laid within each panel in the dividing strip then a roller is rolled on the surface.When the terazzo is completely dry, its grinded and polished using a special machine.8.PVC floor tilesThe tiles come in an average size of 300mm by 300mm ant a thickness varying from 2.5mm to 4mm. The thickness wused will depend on the human traffic that is envisages for the particular floor.These tiles are low cost and come in various colours.Frank Gichuhiwww.a4architect.com

What are the main differences between a 55-300mm lens and a 70-300mm lens in terms of focal length and performance?
The main difference between a 55-300mm lens and a 70-300mm lens is the range of focal lengths they offer. The 55-300mm lens has a slightly shorter focal length range, while the 70-300mm lens provides a longer reach. In terms of performance, the 70-300mm lens may offer better image quality and sharper results at the longer end of the focal length range compared to the 55-300mm lens.
What are the main differences between the Nikon 55-300mm and 70-300mm lenses?
The main differences between the Nikon 55-300mm and 70-300mm lenses are their focal length ranges and maximum apertures. The 55-300mm lens has a slightly shorter focal length range and a smaller maximum aperture compared to the 70-300mm lens. This means that the 70-300mm lens can zoom in closer and allow more light to enter, potentially resulting in better image quality in low light conditions.
What are the main differences between a 70-300mm lens and a 55-300mm lens, and which one would be more suitable for my photography needs?
The main difference between a 70-300mm lens and a 55-300mm lens is the focal length range. The 70-300mm lens has a slightly longer reach at the telephoto end compared to the 55-300mm lens. If you need more zoom capability for shooting distant subjects, the 70-300mm lens would be more suitable. However, if you don't need the extra reach and prefer a slightly wider angle at the lower end, the 55-300mm lens may be a better choice for your photography needs.
