Answer:

Well, each mole of methane CLEARLY contains #12.011*g# of carbon by mass.

Explanation:

And in #23# #mol# of #"methane"#, there are #23*cancel(mol)xx12.011*g*cancel(mol^-1)=276.25*g#.

This is certainly consistent dimensionally. How many grams of hydrogen are there in this molar quantity of methane?
