Well, each mole of methane CLEARLY contains $12.011 \cdot g$ $12.011*g$ of carbon by mass.

And in $23$ $23$ $m o l$ $mol$ of $methane$ $"methane"$ , 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?
