Question
#1. The vapor pressure of methanol (32.043 g/mol), CH3OH, is 94 torr at 20 C. The vapor pressure of ethanol (46.07 g/mol), C2H5OH, is 44
#1. The vapor pressure of methanol (32.043 g/mol), CH3OH, is 94 torr at 20 C. The vapor pressure of ethanol (46.07 g/mol), C2H5OH, is 44 torr at the same temperature. Calculate the total vapor pressure above a solution of 45.1 g of methanol and 46.6 g of ethanol.
#2The enthalpy of solution for HCl(g) (36.46 g/mol) in water is given by Hsol = -74.84 kJ/mol. If 4.76 g of HCl(g) are dissolved in 100.0 g of water (C = 4.184 J/g oC) initially at 20 oC, what with the final temperature of the water be?
