Answer 2

Given : pressure = 249,temperature 27,density = 8.3.

We know that,

$\begin{array}{l}P V=n R T \\P V=\frac{m}{M} R T \\P M=\left(\frac{m}{V}\right) R T\end{array}$

$\begin{aligned}\rho &=\frac{P M}{R T} \\&=\frac{249 \times 10^{6} \times 2 \times 10^{-\not 6}}{83 \times 300}\end{aligned}$

  = $=\frac{249 \times 2}{2490}=0.2 \frac{\mathrm{kg}}{\mathrm{m}^{3}}$

So the the value of $\rho$ is $0.2 \frac{\mathrm{kg}}{\mathrm{m}^{3}}$.
