According to Dalton's law

\mathrm{P_i=x_i P}

\mathrm{\begin{aligned} \text { Let } \omega_{H_2} & =40 \mathrm{~g} \quad n H_2=\frac{40}{2}=20 \\ \omega_{O_2} & =60 \mathrm{~g} \quad n 0_2=\frac{60}{32}=\frac{15}{8} \\ P_{\text{}H_2} & =\frac{20}{\left(20+\frac{15}{8}\right)} \times 2.2 \\ & =2.0114 \\ & \approx 2.016 \mathrm{bar} \end{aligned}}
