The vapor pressure of methanol (32.043 g/mol), CH₂OH, 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 36.3 g of methanol and 46.1 g of ethanol .The enthalpy of solution for HCK(g) (36.46 g/mol) in water is given by AHsol-74.84 kJ/mol If 5.2 g of HCl(g) are dissolved in 100.0 g of water (C = 4.184 J/g °C) initially at 20 °C, what with ?the final temperature of the water be T=____ °C

I need help with these two questions as soon as possible. Please do it neat and clean correctly please posting third time.
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 36.3 g of methanol and 46.1 g of ethanol .The enthalpy of solution for HCK(g) (36.46 g/mol) in water is given by AHsol -74.84 kJ/mol If 5.2 g of HCl(g) are dissolved in 100.0 g of water (C = 4.184 J/g °C) initially at 20 °C, what with ?the final temperature of the water be °C WRO T=
