Explanation / Answer

Moles of magnesium reacted = mass/atomic weight of magnesium

Moles of magensium reacted = moles of H2 gas produced

Trial 1: Moles of magnesium reacted = 0.37/24 = 0.015 moles = Moles of H2 gas produced

Ratio of volume displaced to moles of H2 gas produced = 29.90/0.015 = 1993.33 mL/mol
