At room temp a significant portion of our sample is vaporized, so that when the condensed vapor is weighed, the flask contains sample plus air. The "empty" flask contained only air. The amount of air present during the last weighing is less than the amount in the "empty" flask because some air was displaced by vapor. Would this cause the experimentally determined value of the gram molecular mass to be greater than, less than, or unchanged from the theoretical value? Explain your reasoning.
