# What is the mass of a substance which has a volume of 35 cm^3 and a density of 0.5 g/cm^3?

$D a t a : -$

$V o l u m e = V = 35 c {m}^{3}$
$D e n s i t y = \rho = 0.5 \frac{g}{c {m}^{3}}$

Mass=m=??

Sol:-

We know that:

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

$m = \rho V$

$m = 0.5 \cdot 35 = 17.5 g$
$\implies m = 17.5 g$
