How could you predicd if a block of plastic will float in water?
The block of plastic must be less dense than the water in which it will be placed in order to float. Density is equal to mass over volume (D=m/v), so you could calculate the density of the block of plastic and of a sample of the water by dividing the weight of each sample by the respective volume of each sample. If the density of the plastic is less than the density of the water, it floats! A hint: the maximum density of fresh water occurs at 4 C∘and is equal to 1 gram per 1 milliliter. When a solute - such as salt - is added, the density of water will decrease.
A 25.0ml sample of water at 90Chas a mass of 24.12g calcucate the density of water at this temperature?
0.9648g/ml
A 7.40 cm3 sample of mercury has a mass of 102 g will it float in water?
To solve this question you need to find the sample's density. The formula for density is d=m/v or density = mass divided by volume. You also have to know the density of water, which is 1.so the density of you sample is .2517126 g/cm3because 102 divided by 405.224 (same as 7.403)= .2517126 g/cm3so yes it will float in water because it's density is less than 1 (the density of water).note: because it's less than one doesn't mean it's less dense than all elements. You have to find the less dense element first, and the smaller number will float on the water
Why do biologists use different stains?
A lot of tissue is the same colour and density: have you ever look at glass under water, it is much the same thing. Staining things makes different things take on colour and they can be seen much more clearly. I believe the first medical staining was done by Doctor Erhlich in working with the tuberculosis bacterium.
How do you find the density of a solid if a sample weighing 55.234grams raises the water level in a graduate from 18.6mL to 25.7mL?

Is the density the same or different for each volume of water?
If it is from the same sample, yes. The density of water does vary slightly depending on temperature and any dissolved solutes.
Which is more dense 1 mL of water or 50 L of water?
The answer is: No. Density is a property of a substance, and doesn't depend on the size of the sample. Samples of different sizes all have the same density, as long as they're all samples of the same substance, their compositions are all the same, and the conditions are the same in every case. (Samples of ice and water have different density, because the conditions are different.)
What is the density of 100 gram of water?
The density of water at standard temperature and pressure is 1 gram/milliliter. The size of the sample is irrelevant. If the sample is pure, then one drop of it has the same density as a tankerful of it has.
Does density depend on how much sample you use?
Density is independent of the amount of material in a sample. A sample of a homogeneous substance used to find the density can have any volume. If a cm3 of the substance weighs 8.1 grams, then 10 cm3 will weigh 81.0 grams.We might consider water in a glass or bottle as an example. A small sample will have a given weight (mass) because water has a given density. Ten times that sample volume will have ten times the mass of that volume of water. The density of water does not change if we examine water in a small glass and another sample of the same water in a gallon jug.
What is the mineral property defied by Density of the mineral sample divided by the density of water?
Specific gravity.
What hapens to the density if both the volume and mass are doubled?
If you double the volume of a sample ... scoop up twice as much of it ... the mass of the sample always doubles. But the density of the substance doesn't change. Think about it: The density of some water out of my dog's water bowl is the same as the density of some water out of Lake Michigan.
What would sink first when placed in water?
A sample with high density.
What can you infer about the density of a material if a sample of it floats in water?
it is less dense.
a scientist has a sample of a substance with a volume of 50cm cubed and a mass of 135g. this is most likely a sample og which substance gold, pure water, aluminum or ocean water?
The **density** of a substance is defined as its mass per unit volume. We can calculate the density using the formula: [ \text{Density} (\rho) = \frac{\text{Mass} (m)}{\text{Volume} (V)} ] Given that the sample has a volume of **50 cm³** and a mass of **135 g**, let's determine the density: [ \rho = \frac{135 , \text{g}}{50 , \text{cm³}} ] The calculated density is approximately **2.7 g/cm³**[^10^]. Now let's compare this value to known densities: **Gold**: Gold has a density of *19.3 g/cm³*⁷. The sample's density is significantly lower. **Pure Water**: The density of pure water is approximately **1 g/cm³** at 4.0°C (39.2°F) . The sample's density is higher than water. **Aluminum**: Aluminum has a density of *2.7 g/cm³*[^10^]. The sample's density matches that of aluminum. **Ocean Water**: Ocean water contains dissolved salts, which increase its density. Seawater density typically ranges from *1.02 g/cm³ to 1.03 g/cm³*. The sample's density is higher than seawater. Based on the calculated density, the sample is most likely **aluminum**.
How are density and buoyancy are alike?
If a object has buoyancy it floats. A object also needs to have a density less dense than the object you want it to float on. Example: if you want a inner tube to float and jewelry to sink you make them out of different materials.
How is a sample oxygen different from a sample of a water?
Oxygen is just O and water is H2O
