Homework Help: Chemistry

If you place 10.0 L of propanol (C3H8O) in a sealed room that is 7.5 m long, 3 m wide, and 3 m high,
will all the propanol evaporate? If some liquid remains, how much will there be? The vapor pressure of
propanol is 10.7 torr at 25 C, and the density of the liquid at this temperature is 0.804 g/mL. Treat the
room dimensions as exact numbers

n = PV/RT
(10.7)(67.5)/(0.804)(298.15) = 3.013
