A gas mixture of 4 litres of ethylene and methane on complete combustion at `25^(@)C` produces `6` litres of `CO_(2)`. Find out the amount of heat evolved on burning one litre of the gas mixture. The heats of combustion of ethylene and methane are`-1464` and `-976 KJ mol^(-1)` at `25^(@)C`

Explanation

To solve the problem, we will follow these steps:

### Step 1: Define the variables
Let:
- \( A \) = volume of ethylene (C₂H₄) in the mixture (liters)
- \( B \) = volume of methane (CH₄) in the mixture (liters)

From the problem, we know:
