Well, there are $20 \cdot m o l$ $20*mol$ of hydrogen, so approx. $20 \cdot g$ $20*g$ ........

Explanation:

In one mole of methane we have a mass $16.0 \cdot g$ $16.0*g$ . Carbon constitutes $12 \cdot g$ $12*g$ of this mass, and $4 \cdot g$ $4*g$ of this are hydrogen. If there is a $5.0 \cdot m o l$ $5.0*mol$ quantity of methane, clearly there are $4 \times 5 \cdot m o l$ $4xx5*mol$ hydrogen, and a mass with respect to hydrogen of approx. $20 \cdot g$ $20*g$ . What is the mass of carbon in this quantity?
