question

The dew point (the temperature at which the water vapor in a given sample of air becomes saturated and condensation be-comes possible) of a mass of air at 15°C is 10°C. Calculate the relative humidity and the mass of 1 liter of the moist air if the barometric height is 76 cm of mercury. The gram- molecular weight of air is 28.9 g and the saturated aqueous vapor pressures at 10°C and 15°C are 9.2 mm of mercury and 12.8 mm of mercury, respectively.
