Pressurized metal gas cylinders are generally used to store commonly used gases in the laboratory. At times, it can be easier to chemically prepare occasionally used gases.. For example, oxygen gas can be prepared by heating KMnO4(s) according to the following chemical reaction:
         2KMnO4(s) → K2MnO4(s) + MnO2(s) + O2(g)

The above procedure was carried out starting with 93.2 g of KMnO4, and it was later determined that all of the KMnO4 reacted according to the above equation except 11.7 g. What was the percent yield for the reaction?
