The mass of a substance can be derived from its density. Density is equal to mass per volume, so if volume is known, divide volume by density to get mass.
density = mass/volume If you know density and mass, you can calculate the volume by manipulating the density equation such that volume = mass/density. Example: density = 3.57g/cm3 mass = 2.4g volume = ? volume = mass/density = 2.4g/3.57g/cm3 = 0.67cm3
Height is neither mass nor volume. Height is a measure of how tall something is, mass is a measure of how much matter is in an object, volume is a measure of how much space something takes up. Sometimes height is used to find volume. For example, the volume of a box is equal to the length times the width times the height. The height may even be used to help find the mass. For example, if the density of a box is 3 grams per in2, and the width is 2 inches, the length is 2 inches, and the height is 3 inches, the mass would be volume times density, would would be (2 x 2 x 3) x 3, which would be 36 grams.
it's for finding either the density, mass, or volume of something when given the other two.
mass = volume x density. The units, of course, have to be compatible - for example, if the volume is in cubic meters, and the density in kilograms per cubic meter, the mass will naturally be in kilograms.
