in sample preparation for chemical analysis, H2 is often used to remove oxygen from liquid samples. it can be produced by reacting Fe2O3 with CO gas at high temperatures. The reaction yields Fe and CO2 as byproducts. in an experiment, a reaction mixture containing 75.2g of Fe2O3 and 50.5g of CO produces 0.75g of H2. Determine the precent yield of H2 in this experiment.
