\begin{aligned} & \text { Volume }=5 \times 10^{-3} \mathrm{~m}^3 \\ & \text { mole }=\eta=1+2=3 \\ & \text { Temperature }=300 \mathrm{~K} \\ & P V=n R T \\ & P=\frac{n R T}{V}=\frac{8.314 \times 3 \times 300}{5 \times 10^{-3} } \end{aligned}

     =8.314 \times \frac{3}{7} \times 60 \times 10^3=1.49 \mathrm{MPa}
