`0.22 g` of a hydrogen (i.e., a compound conatining carbon and hydrogen only) on complete combustion with oxygen gave `0.9 g` water and `0.44 g` carbon dioxide. Show that these results are in accordance with the law of conservation of mass (atomic mass of `C = 12, H = 1, O = 16)`.

Explanation

To show that the results of the combustion of a hydrocarbon are in accordance with the law of conservation of mass, we need to analyze the masses of the reactants and products involved in the reaction.

### Step-by-Step Solution:

1. **Identify the Mass of the Reactant:**
The mass of the hydrocarbon (the reactant) is given as:
\[
\text{Mass of hydrocarbon} = 0.22 \, \text{g}
