Question

Which of the following is a correct relation between mass, volume, and density?

• A. $Mass=\frac{Volume}{Density}$
• B. $Density=Mass\times Volume$
• C. $Density=\frac{Mass}{Volume}$
• D. None of these.

Answer 1

The correct option is C

$Density=\frac{Mass}{Volume}$

1. The density of a substance is its mass per unit volume.
2. The mathematical formula for calculating density is:
   $$\begin{gathered} Density=\frac{Mass}{Volume} \\ or \\ D=\frac{M}{V} \end{gathered}$$
3. The SI unit of density is $kg{m}^{-3}$.

Hence, option C is the correct answer.
