According to Dalton's law of partial pressures, the partial pressure exerted by the water vapor in a mixture of air and water vapor is equal to the pressure the water vapor would exert if it alone occupied the total volume of the mixture. If 1.00 m3 of humid air at 20.0°C contains 10.3 g of water vapor, determine
a. The partial pressure of the water vapor.
b. The maximum partial pressure of water vapor at this temperature.
c. The ratio of the answer in part a to that of part b (this ratio is called the relative humidity of the air). .
