Question

What is the density of $5\mathrm{liters}$ of water having mass $5\mathrm{kg}$?

Answer 1

Density: The density of a substance is the ratio of the mass of the substance divided to volume.

• The formula is as follows,
• $\mathrm{Density}=\frac{\mathrm{Mass}}{\mathrm{Volume}}$

Calculation of density

Given,

Volume$=5\mathrm{L}$

mass$=5\mathrm{Kg}$

$$\begin{gathered} \mathrm{Density}=\frac{\mathrm{Mass}}{\mathrm{Volume}} \\ \mathrm{Density}=\frac{5\mathrm{Kg}}{5\mathrm{L}} \\ \mathrm{Density}=1\mathrm{kg}{\mathrm{L}}^{-1} \end{gathered}$$

Hence, the density of water is $1\mathrm{kg}{\mathrm{L}}^{-1}$.
