Question

Solve the problem with complete and proper solution. An object has a density of 5.6 x 10^5 kg/m^3. What is the mass of the object if its volume is 4.5 x 10^-8 m^3?

Answer 1

The mass $m$ can be found as a product of density $\rho$ and volume $V$:

$$m=\rho V,\\ m=(5.6·10^5)·(4.5·10^{-8})=0.0252\text{ kg}.$$
