How to find the percent by mass of a compound in a given sample?
To find the percent by mass of a compound in a given sample, you need to divide the mass of the compound by the total mass of the sample and then multiply by 100. This will give you the percentage of the compound in the sample.
How do you calculate how much water is released in a sample of copper sulfate?
(CuSO4·xH2O) I would suggest heating in a crucible to a constant mass. A simple gravametric calculation using the balanced equation and m=n.gfm will give you a value for x x should be 5
How do you find moles of a chemical with density and molar mass?
You need also to know the volume or the mass of the sample.
What measurement must you make to find the density of a sample of matter?
Two measurements are needed - you must find its mass and its volume. Density is mass divided by volume.
What measurements must you make to find the density of a sample of matters?
density = mass / volume. so you need to weigh to find the mass. To find the volume submerse in water and record the displacement of water to find the volume.

The volume of a sample of water is 20cm3 the mass of?
In order to determine the mass of the water sample, you would need to know the density of water. The density of water is approximately 1 g/cm3. Therefore, the mass of a 20 cm3 sample of water would be 20 grams (20 cm3 * 1 g/cm3 = 20 grams).
How many molecules are in sample 57.45 CF2Cl2?
To calculate the number of molecules in a sample, you need to know the mass of the sample and the molar mass of the compound. Then you can use Avogadro's number (6.022 x 10^23) to convert from grams to molecules.
How many molecules are contained in a 5.00 g sample of dimethylmercury?
To determine the number of molecules in a sample, you need to know the molar mass of the compound. For dimethylmercury, the molar mass is approximately 230.6 g/mol. You can then use the formula n = m/M, where n is the number of moles, m is the mass of the sample, and M is the molar mass, to calculate the number of molecules in the sample.
What is the mass of the 5.6L sample of CH4?
the answer is 4.0 g hope i helped! :)
How many moles of specified particles are present in a sample of N'O if each sample weighs 7.00 g?
To calculate the number of moles of particles present in a sample, you need to divide the sample's mass by the molar mass of the particles. If you specify the particles as N'O, you should provide the molar mass of N'O for an accurate calculation.
