Question

Percent Yield Directions: Please show units and work 1.) What is the percent yield of a product if in an experiment the product weighed 67.3 kg but in the theoretical problem it weighed 44.8 kg? 2.) What is the percent yield if a product weighed 5.3 grams in a real life reaction, but when calculated, it should have weighed 6.4 grams? 3.) 3 Fe3O4 (aq) + 8 Al (aq) -> 9 Fe (s) + 4 Al2O3 (aq) a.) How many grams of Al2O3 are formed if 2 moles of Al and 0.1 moles of Fe3O4 are used? (M.W. of Al is 26.98 g/mol, M.W. of Al2O3 is 101.96 g/mol, and the M.W. of Fe3O4 is 231.533 g/mol) b.) What is the percent yield if the actual yield of Al2O3 is 2846 grams? What about if it was 1994 grams?
