### Quick Answer

**The ratio of mass to volume of a substance is called density.** Units of measure for density include kilograms per meter cubed and grams per centimeter cubed.

Density of a substance is a useful property as it determines whether the substance can float on water. If the density of a substance is less than the density of water, it floats on water; else, it sinks. The density of water is 1 gram per centimeter cubed. It is used as a standard in calculating relative densities of various substances. Relative density is defined as the ratio of the density of a substance to the density of water.

Q:
## How do you find mass?

A:

Full Answer >**Mass is equal to density times volume, or m = Dv, since density is equal to mass divided by volume, or D = m/v.**Mass is denoted by the symbol "m," and its SI units are kilograms.Filed Under: -
Q:
## What is the formula that indicates that volume equals mass divided by density?

A:

Full Answer >**The formula for density, which is mass divided by volume, can be manipulated to have the volume as the unknown.**Given the mass and the density, the volume can be found by dividing the mass by the density.Filed Under: -
Q:
## How do you use mass (in mg) to determine volume occupied?

A:

Full Answer >**To use the known mass of a substance to calculate the volume occupied by that substance, divide the mass by the density of the substance.**The units in which density is expressed must be the same as those used to measure mass and the volume.Filed Under: -
Q:
## How are mass and weight alike?

A:

Full Answer >**Mass and weight are related in that mass is an important factor in calculating weight, but they are not alike.**Mass is the amount of material present in any object, while weight is the measurement of the force with which gravity acts upon the object.Filed Under:
