med from given reactants From the stoichiometry calculation maximum possible amount --Number based upon the theoretical" mathematical equation-ho experients were conducted, Actual Yield - The amount of product that actually when the reaction is carried out in the lab. --- In real life, we never get as much as we anticipate, this actual" amount from the lab experiment. --Due to a variety of factors, the actual amount wilt. WAYS be less than the theoretical yield. Percent Yield - The ratio of the actual vield to the theoretical vield expressed as a percentage Percent Yield Actual Theoretical 100 EXAMPLE) How many grams of hydrofluoric acid (HF) are required to react completely with 23.88 grams of calcium hydroxide in the following reaction? 1 Ca(OH)2 +_2_HF 1 CaFz+_2_H,0 1 mol Ca(OH)2 2 mol HF 20.01 g HF 23.68 g Ca(OH): X 12.79 g HE 74.10 g Ca(OH)2 1 mol Ca(OH)2 1 mol HF Based on the stoichiometry of this problem, the Theoretical Yield for this problem is 12.79 g HF But when this experiment was conducted, an Actual Yield of only 10.41 g HF was collected Using the equation for percent yield, the Percent Yield of this experiment was 81.39% Actual 10.41g HF x 100 = 81.39% Theoretical 12.79g HF Х х Percent Yield * 100 1) A student adds 200.0g of CyH6Os to an excess of C&H60s, this produces CoHuO4 and C2H4O2. Calculate the percent yield if 231 g of aspirin (CsHe04) is produced in an experiment. a barance 200.0g C7H6O3 + _C_H6O3 → __CsH3O4 + C2H4O2 2) According to the following equation, Calculate the percentage yield if 550,0 g of toluene (C-Hs )added to an excess of nitric acid (HNO3) provides 305 g of the p-nitrotoluene (C-H+NO2 product in a lab experiment. C7H8 + HNO3 →_C7H7NO2 + _H20 bungneedy 550.og 3 Aluminum reacts with an aqueous solution containing excess copper (II) sulfate. If 1.85 g Al reacts and the percentage yield of Cu is 56.6%, what mass of Cu is produced? 1.859 Al + _CuSO4 → _Cu + _Al2(SO4)3 4) The combustion of methane(CH) produces carbon dioxide and water. Assume that 2.0 mol of CH4 burned in the presence of excess air. What is the percentage yield if in an experiment the reaction produces 87.0 g of CO2? 2.0 mol
