how to find volume density. Many reference sources are available that give the density of different compounds. Since the density of the metal is 31gcm cubed it means that each cm cubed weighs 31g.
Density is calculated by the dividing the mass by the volume so that density is measured as units of massvolume often gmL. Determine the weight of an object. In our example its 200 cm 3.
200 g 200 cm 3 1 gcm 3.
Since the density of the metal is 31gcm cubed it means that each cm cubed weighs 31g. Determine the density of the substance. When calculating a density from a mass and volume figure its important to remember that density can be affected by pressure and temperature particularly where gases are concerned. A 500ml jug full of feathers or a 500ml jug full of lead then the answer would be the lead.
