Question

If the mass of a substance having its volume 80 cm is 68 g. Calculate the density of the substance​

Answer 1

`\text{Given that,}\\\\\text{Mass}~ m = 68 ~\text{g} = 68 * 10^(-3)~ \text{kg}\\\\\text{Volume}~ V = 80 ~ \text{cm}^3 = 80 * 10^(-6)~ \text{m}^3 = 8* 10^(-5)~ \text{m}^3\\\\\\\text{Density} ~\rho = \frac mV = (68* 10^(-3))/(8 * 10^(-5)) = 8.5 * 10^2 = 850 ~ \text{kg}~\text{m}^(-3)`
