The partial pressure of ethane over a solution containing \( 6.56 \times 10^{-2} \mathrm{~g} \) of ethane is \( 1 \mathrm{bar} \). If the solution contains 5.00 \( \times 10^{-2} \mathrm{~g} \) ethane, then partial pressure
(a) 1.312 bar
(b) 1.0 bar
(c) \( 0.762 \mathrm{bar} \)
(d) \( 0.912 \mathrm{bar} \)
