Volume of Hydrogen gas, you given the following data: Mass of Mg = 0.02 g.
(atomic mass of Mg = 24.30 g/mole)

Volume of the gas in the calibrated part = 33.5 ml

Volume of the gas in the uncalibrated part= 8.20 mL. Room temperature= 18.60 oC.
Atmospheric pressure = 630.0 torr.
Water's temperature = 22.500C.
Vapor pressure of water = 19.00 torr at t = 22.500C

Calculate the molar volume of Hydrogen gas (in L/mole) at STP.​
