Question:

The best way to generate small amounts of oxygen gas in a laboratory setting is by the decomposition of potassium permanganate:

2 KMnO4(s)  KMnO4(s) + MnO (s) + O(g).


Suppose that you are carrying out an experiment for which you need exactly 2.00 L of oxygen. Describe how you would determine the mass of potassium permanganate needed to obtain this amount of oxygen. What would you have to measure in your experiment in addition to this mass?
