Question

A sample of cobalt has a mass of 27 g and a density of 9 g/cm^3. What would be its volume?

Answer 1

given ,

Mass of sample of cobalt = 27 g

density of sample of cobalt = 9g/cm^3

We know that ,

Density = mass of sample/volume of sample

From that relation ,

We can deduce the following as

Volume = mass of sample/density of sample

Hence , required volume of sample of cobalt = 27 g /9 g/cm^3 = 3 cm^3

The volume is $\fbox{3cm cube}$
