`3 g` of ethane `C_(2)H_(6)` on complete combustion gave `8.8 g` of `CO_(2)` and `5.4 g` of water. Show that the results are in accordance with the law of conservation of mass.

Explanation

To show that the results are in accordance with the law of conservation of mass, we will follow these steps:

### Step 1: Write the balanced chemical equation for the combustion of ethane (C₂H₆).
The balanced equation for the complete combustion of ethane is:
\[ 2 \text{C}_2\text{H}_6 + 7 \text{O}_2 \rightarrow 4 \text{CO}_2 + 6 \text{H}_2\text{O} \]
