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)

How many grams of KMnO4 would you need to produce 0.27 moles of O2, assuming 100% conversion? The molar mass of KMnO4 is 158.034 g/mol.
