A gas sample collected over water at a pressure of 364.1 mmHg and occupies 35.27 mL at 27.0 °C. If the gas is then dried and the volume remains constant what will be the pressure of the gas (in atm) when the temperature is changed to 49.5 °C?

I can't answer your question yet, but something I learned today in my chem class was the cold and dry air weigh more than warm and wet air... :) So your answer for the mass will be lighter.
