Question

The density of a given mass of 500g and volume 1000mm³ is given by?

Answer 1

By definition, the dinsity of the body is given as the ratio of its mass and volume:

$$\rho = \dfrac{m}{V}$$

Since $m = 500g$ is the mass, and $V = 1000mm^3 = 1cm^3$ the density will be:

$$\rho = \dfrac{500g}{1cm^3} = 500\dfrac{g}{cm^3} = 5\times 10^5\dfrac{kg}{m^3}$$

Answer. 500 g/cm^3 or 5*10^5 kg/m^3.
