2KNO3 ==> 2KNO2 + O2
The equation above is not necessary for solution of the problem.
Use PV = nRT and solve for n.
When a sample of potassium nitrate is heated, oxygen gas is produced. This gas, collected in a 750 milliliter flask, has a pressure of 2.8 atmosphere and the temperature is recorded to be 53.6°C. How many moles of oxygen gas are produced in this reaction?
(R = 0.08205 L atm/K mol)
