A hydrocarbon contains 82.8% of carbon and has a relative molecular mass of 58. Write its empirical formula.

Explanation

To find the empirical formula of the hydrocarbon that contains 82.8% carbon and has a relative molecular mass of 58, we can follow these steps:

### Step 1: Determine the percentage of hydrogen
Since the hydrocarbon is made up of carbon and hydrogen, we can find the percentage of hydrogen by subtracting the percentage of carbon from 100%.

\[ \text{Percentage of Hydrogen} = 100\% - 82.8\% = 17.2\% \]
