Question

Calculate the density of $N{H}_3$ at ${30}^{\circ }C$ and 5 atm pressure.

• A. 2.43 gm/lit
• B. 3.42 gm/lit
• C. 22 gm/lit
• D. 0.03 gm/lit

Answer 1

The correct option is B 3.42 gm/lit

$PV=nRTor,PV=\frac{\omega }{M}RT$
$\Rightarrow PM=\frac{\omega }{V}RT\Rightarrow PM=DRT$
$D=\frac{MP}{RT}=\frac{17\times 5}{0.082\times 303}=3.42gm/lit$
