A chemist ran the reaction CH3CH2Cl(l) + KOH(aq) ^ CH3CH2OH(l) +KCL(aq) by heating 47.2 grams of CH3CH2Cl with excess KOH and obtained a yield of 28.7 grams of CH3CH2OH. What was his % yield?

I do not know where to begin with this problem. It only gives grams of one reactant? What is the actual yield? Detailed step by step instructions please.
