Unknown gas in cylinder chemistry problem?

A cylinder of compressed gas rolls off a boat and falls to the bottom of a lake. Eventually it rusts and the gas bubbles to the surface. A chemist collects a sample of the gas with the idea of trying to identify the gas. The wet gas collected occupies a volume of 281 mL at a pressure of 710 torr and temperature of 28.0oC. The vapor pressure of water at 28.0oC is 0.0372 atm.

1. Calculate the volume (L) that the gas occupies after it is dried (the water vapor removed) and stored at STP.


I think I have to use P1V1/n1T1 = P2V2/n2T2 but I'm lost after that. Can someone help me out?
