(A) Moles of first gas $n_1 = \frac{w_1}{m_1} = \frac{0.45}{60} = 0.0075 \ mol$. Moles of second gas $n_2 = \frac{w_2}{m_2} = \frac{0.22}{44} = 0.0050 \ mol$. Total moles $n_{total} = n_1 + n_2 = 0.0075 + 0.0050 = 0.0125 \ mol$. Partial pressure of the second gas $P_2 = \left( \frac{n_2}{n_{total}} \right) \times P_{total} = \left( \frac{0.0050}{0.0125} \right) \times 75 = 30 \ cm \ of \ Hg$.
