問題如下: Benzene and toluene form an ideal solution. At 298 K, what is the mole fraction of benzene in the liquid that is in equilibrium with a vapor that has equal partial pressures of benzene and toluene? At 298 K, the vapor pressures of pure benzene and pure toluene are 95 and 28 torr, respectively. 我現在如果設x是mole fraction of benzene 然後1-x 就是mole fraction of toluene 所以Ptotal = (x)(95 torr) + (1-x)(28 torr) 可是我現在不知道Ptotal是多少? 有沒有大大可以幫幫我的? 謝謝喔^^ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 68.181.217.58

95x=25(1-x) equal parital pressures??
