(A) Let the mass of $H_2$ be $w \ g$ and the mass of $O_2$ be $2w \ g$.Number of moles of $H_2$ $(n_{H_2})$ = $\frac{w}{2}$.Number of moles of $O_2$ $(n_{O_2})$ = $\frac{2w}{32} = \frac{w}{16}$.Total moles $(n_{total})$ = $\frac{w}{2} + \frac{w}{16} = \frac{8w + w}{16} = \frac{9w}{16}$.Mole fraction of $O_2$ $(x_{O_2})$ = $\frac{n_{O_2}}{n_{total}} = \frac{w/16}{9w/16} = \frac{1}{9}$.Partial pressure of $O_2$ = $x_{O_2} \times P_{total} = \frac{1}{9} \times p = \frac{p}{9}$ atm.
