SOLVED: A frequently used method for preparing oxygen in the laboratory is by the thermal decomposition of Potassium Chlorate (KClO3). Use the equation provided to answer the questions below. KClO3 (s) → KCl (s) + O2 (g) 1. How many grams of O2 (theoretical yield) can be produced from 5.00 x 10-2 moles of KClO3? 2. Using the theoretical yield from the previous problem; if the actual yield of O2 was 2.278g, then what would be the percent yield of O2?
