The volume of a sample of water is 20 cm3. The mass of this sample is closest to
mass= volume*density. water density is about a gram per cc
(HELP ME)a secientist has two samples of a substance.both samples have the same temperature.one sample has a mass of 10g. the other sample has a mass of 20g. compare the average kinetic energy and total kinetic energy of the particles ineach sample.
To determine the mass of a sample of water, we need to know its density.
The density of water is approximately 1 gram per cubic centimeter (g/cm^3). Therefore, we can assume that the density of the water sample in question is 1 g/cm^3.
To find the mass (in grams) of the water sample, we can use the formula:
Mass = Density x Volume
Given that the volume of the water sample is 20 cm^3 and the density is 1 g/cm^3, we can substitute these values into the formula:
Mass = 1 g/cm^3 × 20 cm^3
Mass = 20 grams
Therefore, the mass of the water sample is closest to 20 grams.
