    What Is the Volume of Dry Hydrogen Gas at STP?

    Homework Statement A 32.0 mL sample of hydrogen is collected over water at 20°C and 750.0 torr pressure. What is the volume of the dry gas at STP? (vapor pressure of water at 20°C = 17.5 torr) Homework Equations Ptot = Pdry + Pwet P1V1/T1 = P2V2/T2 The Attempt at a Solution...
