Data: Reaction of Mg (s) with HCI Mass of magnesium metal Temperature of the gas in flask A (The temperature of the solution in flask A) Temperature of the gas in flask B (The temperature of the solution in flask B) Average temperature of the gas Volume of hydrogen gas collected Barometric pressure Water vapor pressure at the average temperature of the gas (see Appendix 1, interpolate the value) 0.1335 42.2°C 22.3°C 32.250 261mL 763 mm На 36.999 mmH

Part 2. The molar volume of hydrogen. Make a table (as shown) in your lab notebook to do calculations. Data Calculations Mass of magnesium Moles of hydrogen Average temperature of gas (absolute, K) Pressure of hydrogen, PH₂ Volume of H₂ at STP (calculate this from your data) Molar volume of H₂ at STP (L/mol)
