$\displaystyle 5.1 \mathrm{~g} \mathrm{NH}_4 \mathrm{SH}$ is introduced in $\displaystyle 3.0$ L evacuated flask at $\displaystyle 327$°C. $\displaystyle 30$% of the solid $\displaystyle \mathrm{NH}_4 \mathrm{SH}$ decomposed to $\displaystyle \mathrm{NH}_3$ and $\displaystyle \mathrm{H}_2 \mathrm{~S}$ as gases. The $\displaystyle \mathrm{K}_{\mathrm{p}}$ of the reaction at $\displaystyle 327$°C is $\displaystyle \left(\mathrm{R}=0.082 \mathrm{~L} \mathrm{~atm} \mathrm{~mol}^{-1} \mathrm{~K}^{-1}\right.$, Molar mass of $\displaystyle \mathrm{S}=32 \mathrm{~g} \mathrm{~mol}^{-1}$, molar mass of $\displaystyle \mathrm{N}=14 \mathrm{~g} \mathrm{~mol}^{-1}$ )
