    1. The problem statement, all variables and given/known data

    Calculate the average ratio of grams of hydrogen gas produced per gram of magnesium. This is part of a lab in which I know how many grams of magnesium were used and how many ml of hydrogen gas was produced

    2. Relevant equations

    Mg (s) + 2 HCl ---> MgCl2 + H2

    3. The attempt at a solution

    Well, you have not posted any experimental data, so the question - as posted - doesn't make much sense.

    Convert hydrogen volume to number of moles, number of moles to mass.
