How many moles of KClO3 must decompose in order to produce 9 moles of oxygen gas (O2) using the following reaction by completing the t-chart below.

6 moles of will be decomposed.

Explanation:

We are given:

Moles of oxygen gas produced = 9 moles

The chemical equation for the decomposition of follows:

By the stoichiometry of the reaction:

If 3 moles of oxygen gas is produced by 2 moles of

So, 9 moles of oxygen gas will be produced by = of

Hence, 6 moles of will be decomposed.
