    1. Magnesium reacts with oxygen to form magnesium oxide
    2Mg(s) + O2 > 2MgO(s)
    Calculate the volume of oxygen that would be required to react with 1.20g of magnesium.
    (1mole of a gas has a volume of 24dm^3 under the conditions in this experiment)

    The number of moles of oxygen gas needed can be found by comparing with the number of moles of Magnesium needed, so you need to work that out first, then by looking at their ratios in the equation will help find the moles of oxygen. Then Volume = mol x 24
