Magnesium oxide can be made by heating magnesium metal in the presence of oxygen. The balanced equation for the reaction is:

2 Mg (s) + O2(g)      →       2 MgO (s)

When 10.1 g of Mg reacts with 10.5 g O2 , 11.9 g MgO is collected. Determine the limiting reactant, theoretical yield and percent yield for the reaction.
