Short Answer
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 of KMnO4(s)should be decomposed? Assume the decomposition of KMnO4(s)goes to completion.
