10. At 63.5度C, the vapor pressure of H2O is 175 torr, and that of ethanol,
C2H5OH, is 400 torr. Assuming ideal-solution is formed by mixing equal
moles of H2O and C2H5OH at 63.5度C.
(a) The mole fraction of ethanol in the solution is 0.500.
(b) The partial pressure of ethanol over the solution is 200 torr.
我想請問以上兩小題的計算過程
