i think its about 43.45
its millilitres
Depending on how accurate you want to be you can use a variety of methods. Common methods include the following (with increasing level of accuracy) 1) graduated cylinder 2) volumetric pipette. 3) Calibrated micro-pipette (may require more than one transfer)
A graduated cylinder is a piece of laboratory glassware used to accurately measure out volumes of chemicals for use in reactions. They are generally more accurate and precise for this purpose than beakers or erlenmeyer flasks, although not as precise as a volumetric flask or volumetric pipet. They come in a variety of sizes for different volumes, typically 10 mL, 25 mL, 50 mL, or 100 mL and up to as large as 1 or 2 liters.Determine the volume contained in a graduated cylinder by reading the bottom of the meniscus at eye level.In other words, holding the graduated cylinder at eye level, the bottom of the curved surface of the liquid (called the meniscus) is where you read off the mark on the graduated cylinder to determine the volume properly.
The range of a graduated cylinder refers to the volume of liquid it can accurately measure, which typically spans from its minimum to maximum capacity. Graduated cylinders come in various sizes, commonly ranging from 10 mL to 2,000 mL or more. The accuracy and precision of measurements depend on the cylinder's design and the scale markings. It's essential to use a graduated cylinder that suits the specific volume you need to measure for optimal results.
The best way to find a volume of anything(that doesn't dissolve or get damage by water) is by simply filling a graduated cylinder with water(amount doesnt matter)then dipping the object in water and calculating the difference. (FOR EXAMPLE: I can fill a graduated cylinder up to 100 ml. Then i will dip the expo marker in it. And let's say for example that it rises by 50 ml. Then the volume is 50 milliliters.)
A 50-mL graduated cylinder marked into 1-mL segments would have markings at every 1 mL increment from 0 to 50 mL. This means it would have a total of 50 markings on the cylinder at every 1-mL interval.
The mass of an empty 10 ml graduated cylinder typically ranges from 20 to 30 grams, depending on the material it is made of (glass, plastic, etc.).
Either a 100 mL or a 50 mL The 50 mL is better because you can see the meniscus against the graduated lines of the cylinder better.
The mass of water added is 110 g minus the initial empty cylinder mass. The mass of the rock is the total mass of 250 g minus the mass of the water and empty graduated cylinder. The density of the rock can then be calculated using the mass of the rock and its volume (37 mL - 30 mL).
You would need a graduated cylinder or a measuring cup to accurately measure 50 ml of water.
The smallest measurement on a graduated cylinder depends on the particular cylinder, since different sizes and brands exist. A common unit to measure by in a graduated cylinder is 1/100th of a liter.
You would likely use a graduated cylinder to measure out and transfer the 50 mL of stock solution to the reaction vessel. Graduated cylinders are specifically designed for measuring and transferring liquid volumes accurately.
The volume of 12.0000 mL would be recorded as 12.00 mL when measured from a 50-mL graduated cylinder because the cylinder has markings in increments of 1 mL. It is standard practice to record the volume to two decimal places for greater accuracy.
The mass of water can be determined by multiplying the volume of water by its density. Given that the density of water is 1.0 grams per cubic cm, and the volume of water is 50 ml, the mass of the water would be 50 grams.
50 ml is 50/1000 of a litre. Whether of not you use a graduated cylinder (however you choose to spell the word) is irrelevant.
To measure 12.0000 ml from a 50 ml graduated cylinder, fill the cylinder past the 12 ml mark and then carefully pour out the excess liquid until the bottom of the meniscus is exactly at the 12 ml mark. Be cautious and precise when pouring to achieve an accurate measurement.
The rock's volume is simply the amount of water the rock displaced (52mL - 32mL), so 20mL. The density is mass over volume, so 40g/20mL, which simplifies to 2 g/mL: 40 divided by 20 is 2, and then the unit is just mass (g) over volume (mL).
