Chapter 20, Problem 21A

Calculate the density of a gas with a mass of 4.29 kg and a volume of 3.0 cubic meters. Express your answer in $kg/m^3$.

To determine

Density of gas.

Answer to Problem 21A

Density of gas is $\rho =1.43{\text{kg/m}}^3$

Explanation of Solution

Given:

Mass of gas, $m=4.29\text{kg}$

Volume of gas, $V=3{\text{m}}^3$

Formula Used:

The density is given as,

  $\rho =\frac{m}{V}$

Where, $\rho$ is density, $m$ is mass and $V$ is volume.

Calculation:

On substituting the given values in above relation,

  $\begin{array}{l}\rho =\frac{4.29}{3}{\text{kg/m}}^3\\ \Rightarrow \rho =1.43{\text{kg/m}}^3\end{array}$

Conclusion:

Therefore, the density of gas is $\rho =1.43{\text{kg/m}}^3$
