Look at the ratio of hydrogen to carbon in propane......

Explanation:

For every "8 hydrogens" in propane there are "3 carbons".

And thus if there are 8.48xx10^24 hydrogen atoms, there are 3/8xx8.48xx10^24 carbon atoms, approx. 3xx10^24 carbon atoms. What is the mass of this quantity of carbon atoms?
