The balanced chemical reaction is given above however I believe the coefficients are wrong. It should be:

4K + O2 = 2K2O

We use data from that reaction to obtain relationships between substances. We are given the amount of potassium that reacts. We proceed as follows:

1.52 mol K (2 mol K2O / 4 mol K) = 0.76 mol of K2O is formed
