To find the molecular formula of the brominated alkane given the percentages of carbon and hydrogen, as well as the vapor density, we can follow these steps: ### Step 1: Determine the percentage of bromine We know the total percentage must equal 100%. Given that the percentages of carbon and hydrogen are 12.8% and 2.1%, respectively, we can find the percentage of bromine. \[ \text{Percentage of Bromine} = 100\% - (\text{Percentage of Carbon} + \text{Percentage of Hydrogen}) \] ...
