The amount of an object does not change the density. ... The density (d) of a material is its mass (m) divided by its volume (V). ... Calculate the density of an object that has a mass of 25.0g and the volumeis 10.5ml. ... If you know that the object has a density of 20.0 g/ml and the volume is 5.00 ml. ... 40g/12cm3 =3.3 g/cm3 ...
