Question

 substance has a mass M= 500 kg and a volume V=0.215 m3. Find 

Answer 1

To be given in question

Mass (m)=500kg

Volume (v)=0.215 $m^3$

To be asked in question

Density=?

We know that

Density=ratio of mass and volume

$d=\frac{m}{v}\rightarrow(1)$

Put value equation (1)

$d=\frac{500}{0.215}kg/m^3$

$d=23.25\times10^{2}kg/m^3$
