I have no idea where to start. Any help would be greatly appreciated.
Given: The temperature is 26C and the partial pressure of the water vapor in the air is 31.0 torr. The 9000 ton air conditioning system maintains an inside air temperature of 26C also but has a partial pressure of water vapor of 10.0 torr. The volume of air in the dome is 2.45x10^6m^3
and the total pressure inside and outside the dome are both 1.0 atm

Questions:
a) What mass of water must be removed every time the inside air is completely replaced with outside air?

b) Find the heat released when this mass of water condenses.
