2KClO3 -> 2KCl + 3O2
The reaction above took place and 3.25 liters of oxygen gas were collected over water at a temperature of 27*C and a pressure of 765 milimeters of mercury. The vapor pressure of water at 27*C is 30.0mm of mercury. What is the partial pressure of the oxygen collected?
and
What was the mass of KClO3 consumed in the reaction?
