How many moles of KCIO,(s) must be decomposed to yield 15 moles O2(g)? 2 KCIO,(s) 2 KCI) + 3 02(g)

Explanation:

2 KCIO,(s) 2 KCI) + 3 02(g)

 For every 3 moles of O2 you need 2 moles of KClO3

2/x = 3/15               Cross Multiply

3*x = 2 * 15             Combine the right

3x = 30                  Divide by 3

3x/3 = 30/3             Combine

x = 10
