A 550 mL sample of Oxygen gas is collected over water at a temperature of 21.0 degree Celsius as well as a pressure of 743 mmHg according to the following reaction. Vapor pressure of water at 21.0 degree Celsius = 18.7 mmHg, 1 atm = 760 mmHg
2KClO3 (s) --> 2KCl (s) + 3O2 (g)
a. Explain how many mols of Oxygen were collected?
P total = Poxygen + P watervapor
b. Explain how many grams of potassium chlorate reacted?
