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, 5.00
L of N2 gas is passed through 7.2146 g of liquid benzene
1C6H62 at 26.0 °C. The liquid remaining after the experiment
weighs 5.1493 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?
