A convenient way to produce very high purity oxygen in the laboratory is to decompose KMnO4(s) at high temperature according to the following chemical equation:
         2KMnO4(s)  →  K2MnO4(s) + MnO2(s) + O2(g)
If 2.50 L of O2(g) is needed at 1.00 atm and 20.°C, what mass (in grams) of KMnO4(s) should be decomposed? Assume the decomposition of KMnO4(s) goes to completion.
