Mass to Mass Problems

If I start with 89.0 grams of sulfuric acid and produce 7.10 grams of water, what is my percent yield? (~43%) Theoretical Yield = how much product supposed to be formed theoretically – calculated using molar ratio. Actual Yield = experimental yield of product – given in the question % Yield = Actual Yield__ x 100%. Theoretical Yield . AY. TY %Y ................
