It is understood that more carbon atoms present in a hydrocarbon, the greater the density of the hydrocarbon.
But then why does $\mathrm{CH_{3}I}$ have a greater density than $\mathrm{C_{2}H_{5}I}$?

For the same reason why a bucket of sand will weigh more than a bucket of rocks. Smaller molecules will result in a more dense, thus more heavy substance.
