*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?
我第一小題是用PM=DRT算的 算出P=0.61atm=461.17torr
然後第二小題我就把上面的壓力乘以水的莫耳分率
1000/18
=461.17*--------------=460.25(torr)
0.1+(1000/18)
但算完就覺得不太對應該考慮飽和蒸汽壓
要怎麼樣才能求出飽和蒸汽壓呢?? 然後要怎樣完成這一題呢請大大指教謝謝
*還有可以再請問一下什麼是critical temperature of noble gases?
