Could someone please help me with this problem? I need to know the answer, so that I can make sure I solve it correctly once I try to do it on my own... But knowing the process is what's most important. So, I would appreciate if someone gave me the answer and walked me through how they got there. I am most confused about theoretical yields, if that makes any difference! :) Thanks in advance. 

Given the following chemical equation, if 162.0 grams of potassium reacts with excess oxygen gas and was found to produce 172 grams of potassium oxide, what is the percent yield for this reaction?

4 K(s) + O2(g) -->  2K2O(s)
