Eview the equation below. 2kclo3 2kcl + 3o2 how many moles of oxygen are produced when 2 mol of potassium chlorate (kclo3) decompose?

3 mol O2. The decomposition of 2 mol of KClO3 produces 3 mol of O2.

(a)Use the balanced equation to find the molar ratio of O2:KClO3.

Molar ratio = 3 mol O2:2 mol KClO3

(b)Use the molar ratio to calculate the moles of O2.

Moles of O2 = 2 mol KClO3 x (3 mol O2/2 mol KClO3) = 3 mol O2

the temperature of the gas, in k, not celsius.
