Answer:

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?
