Show how each of the following errors would affect (increase, decrease or no change) your calculated value for the molar volume of O2 at STP (Presuming that you complete the experiment otherwise correctly).
A. Your sample wasn't completely decomposed.
B. Subsequent to you finish heating your sample as well as the system cooled to room temp, you closed the clamp on the tube D without re-equalizing the pressures inside as well as outside of the flask. The water in beaker E was 4 in. deep as well as the water in flask C was 2 in deep.
