1 atm = 760 mmHg
912 mmHg * (1 atm/760 mmHg) = 1.2 atm
We are limited to 3 significant digits from 912 mmHg, so your final answer will be 1.20 atm.
The first step is to focus on the parent carbon chain:nonane. This indicates a carbon chain with 9 carbon atoms. From here, on the 4th carbon from one side, place a Br functional group; on the 2nd carbon, place a I functional group; on the 5th and 6th carbon, place a CH₃ (methyl) functional group to each. Lastly, complete the bonding with H atoms. The structure is shown in the attached picture.
