1Mole of methanol, when burnt in oxygen gives out `-723 KJmol^(-1)` heat. If 1 mole of oxygen is used what will be the amount of heat evolved?

Explanation

To solve the problem, we need to determine the amount of heat evolved when 1 mole of oxygen is used in the combustion of methanol. We know that burning 1 mole of methanol releases -723 kJ of heat when 3.2 moles of oxygen are used.

### Step-by-Step Solution:

1. **Understand the Reaction**:
The combustion of methanol (CH₃OH) can be represented by the balanced equation:
\[
\text{CH}_3\text{OH} + \frac{3}{2} \text{O}_2 \rightarrow \text{CO}_2 + 2 \text{H}_2\text{O}
