Pressure of H, gas: Assume that water and molecular hydrogen are the only gases inside the tube.
Using the measured atmospheric pressure and the partial pressure of water vapor (determined from
the temperature - see Appendix 3), calculate the pressure of molecular hydrogen gas for each trial.
Trial 1: Patm=29,39inHgx254cmx10mm-746.506mmHg

Moles of H,gas: Using the molar mass of magnesium and the balanced equation for the reaction
you have just observed, calculate the moles of molecular hydrogen that should have been formed.
This calculation assumes that the magnesium was pure and was completely consumed by the
hydrochloric acid, and that no H₂ was lost in the process (i.e., it assumes a 100% yield of hydrogen
gas).
