Chemistry Help Vapor Phase?

A glass beaker containing 100 ml of Toluene breaks in a small, unvented storage cabinet with a volume of one cubic meter. The ambient temperature of the liquid toluene and the inside of the storage cabinet is 25C. Assuming toluene can be treated as an ideal gas in its vapor phase, what is the expected concentration (in parts per million) of toluene in the storage cabinet assuming that all the toluene vaporized and none was lost outside the storage cabinet?
