Solution: The vapor pressure of a volatile liquid can be determined by slowly bubbling a known volume of gas through it at a known temperature and pressure. In an experiment, 5.01 L of N2 gas is passed through

Problem

The vapor pressure of a volatile liquid can be determined by slowly bubbling a known volume of gas through it at a known temperature and pressure. In an experiment, 5.01 L of N2 gas is passed through 7.5001 g of liquid benzene, C6 H6, at 27.6 oC and atmospheric pressure. The liquid remaining after the experiment weighs 5.5001 g .

Assuming that the gas becomes saturated with benzene vapor and that the total gas volume and temperature remain constant, what is the vapor pressure of the benzene in torr?
