Question

What is the density of the material of an utensil whose volume and mass are $10c{m}^3$ and $100g$ respectively?

• A. $10g/c{m}^3$
• B. $8g/c{m}^3$
• C. $12g/c{m}^3$
• D. $9g/c{m}^3$

Answer 1

The correct option is A $10g/c{m}^3$

The unchanging relation between the mass of an object ($m$), its volume ($v$) and density ($d$) of the material, is given by $m=d\times v$.

Given $v=10c{m}^3$, $m=100g$. Then its density is,

$d=\frac{m}{v}=\frac{100}{10}=10$.
Therefore, density of the material is $10g/c{m}^3.$
