Detailed explanation-1: -Problem 1: You have a rock with a volume of 15cm3 and a mass of 45 g. What is its density? Density is mass divided by volume, so that the density is 45 g divided by 15cm3, which is 3.0 g/cm3.
Detailed explanation-2: -The mass of a substance is measured using a balance. The volume of a liquid can be measured using a graduated cylinder, pipet, or buret, while the volume of a gas can be measured with a gas syringe.
Detailed explanation-3: -Specific gravity, which is virtually identical to density, is the ratio of the weight of a substance (mineral sample) to the weight of an equal volume of water at a specified temperature.
Detailed explanation-4: -What is the volume of a sample of liquid mercury that has a mass of 76.2 g, given that the density of mercury is 13.6 g/mL? The answer would be 5.60 mL because 76.2 g divided by 13.6 g/mL is 5.60 mL.
