2KClO3 + heat -----> 2KCl + 3O2
If I have 5g of KCLO3, how many moles of gas are formed? If the volume obtained was 500mL at a temperature of 22°C, what is the pressre of 02? What is the total system pressure? (takes into account the water vapor pressure)
Homework Answers
Total system pressure is (1+1.93) ATM = 2.93 ATM
Please check the calculations and pay attention to the unit analysis.

Oxygen gas can be prepared by heating potassium chlorate: 2KClO3(s)2KCl(s) + 3O2(g) In one experiment, a sample of KClO3 reacts and the gas produced is collected by water displacement. The gas sample has a temperature of 23.00 °C, a volume of 769.0 mL, and a pressure of 742.0 mm Hg. Calculate the amount (in moles) of oxygen gas produced in the reaction. The vapor pressure of water is 21.07 mm Hg at 23.00 °C.
