Actual Yield = The amount of product that . actually. forms when the reaction is carried out in the lab.--Due to a variety of factors, the actual amount will ALWAYS be less than the theoretical yield.---In real life, we never get as much as we anticipate, this “actual” amount from the lab experiment. Percent Yield = The . ratio

b) I got a percent yield of 75% How many grams of water did I make? 3) Be + 2 HCl ( BeCl2 + H2. My theoretical yield of beryllium chloride was 10.7 grams. If my actual yield was 4.5 grams, what was my percent yield? 4) 2 NaCl + CaO ( CaCl2 + Na2O. What is my theoretical yield of sodium oxide if I start with 20 grams of calcium oxide?

Determine how much excess was USED to produce the theoretical yield. (Use mole ratios here again) Subtract the amount of excess reactant you STARTED with – what you USED. To find the % yield of an EXPERIMENT, you must take the actual yield (experiment)/ theoretical yield (determined in step 3) and x 100
