We’re being asked to calculate the actual yield of Mg(NO3)2 in the reaction if the efficiency (percent yield) is 30.60%

The balanced chemical equation is:

Mg + Cu(NO3)2 Mg(NO3)2 + Cu

Recall that percent yield is given by:

The theoretical yield is not given but we can use the given information: 140.2 g Mg reacts with excess Cu(NO3)2.
