A hydrocarbon contains 17.2% H. If the vapour density is 29, calculate its molecular formula.

Text Solution

AI Generated Solution

To find the molecular formula of the hydrocarbon given that it contains 17.2% hydrogen and has a vapor density of 29, we can follow these steps: ### Step 1: Determine the percentage of carbon Since the hydrocarbon only contains hydrogen and carbon, we can calculate the percentage of carbon by subtracting the percentage of hydrogen from 100%. \[ \text{Percentage of Carbon} = 100\% - 17.2\% = 82.8\% \] ...
