Question

A 6.0-mol sample of KClO3 was decomposed according to the equation 2KClO3 --> 2KCl + 3O2. How many moles of O2 are formed?

9.0 mol
2.5 mol
6.0 mol
4.5 mol

Answer 1

2.5 mol is the answer

Step-by-step explanation:

hope it will help you..

Answer 2

9 moles of O2

• Balanced equation: 2KClO3 --> 2KCl + 3O2

given:

6.0-mol of KClO3

using molar ratio:

2KClO3 : 3O2

2 : 3

moles of O₂ = ( 6/2 ) * 3 = 9 moles
