Question

A sample of a certain material has a mass of 2.03 x 10-3 g. calculate the volume of the sample, given the density is 9.133 x 10-1 g/cm3.

Answer 1

Mass of a sample = M = 2.03 x 10-3 g

Density of a sample = D = 9.133 x 10-1 g/cm3

Volume of the sample = ?

By using the formula = D = M / V

V = M / D

Putting the values of density and mass of the sample

V = 0.00203/0.9133 = 0.0022cm3

V = 0.0022 cm3
