标题Re: [化学] 蒸气压的问题
时间Sat Jul 19 01:39:16 2008
※ 引述《vivaonly (viva)》之铭言:
: *The density of water vapor in eqilibrium with liquid water at 60度C
: is 1.40 g/L. What is the vapor pressure (in torr) of water at 60度C?
: And what is the vapor pressure of 0.1m NaCl aqueous solution at 60度C?
: 我第一小题是用PM=DRT算的 算出P=0.61atm=461.17torr
: 然後第二小题我就把上面的压力乘以水的莫耳分率
: 1000/18
: =461.17*--------------=460.25(torr)
: 0.1+(1000/18)
: 但算完就觉得不太对应该考虑饱和蒸汽压
: 要怎麽样才能求出饱和蒸汽压呢?? 然後要怎样完成这一题呢请大大指教谢谢
饱和蒸汽压要查表吧
: *还有可以再请问一下什麽是critical temperature of noble gases?
钝气的临界温度
