Jessica is doing her pre-lab homework for Chemistry. She is asked to predict how many grams of oxygen gas are produced if 40.0 g of potassium chlorate is decomposed according to this balanced chemical equation shown. 2KCIO3(s)-2KCI(s)+302(g) She performs the following calculation, and gets 15.7 g of O2 as her answer. The next day when her group performs the experiment they obtain an actual yield of 14.5 grams of oxygen gas. What is the percent yield for the experiment? report your answer to the tenths place, i.e. one decimal place.
