Explanation:

Start by determining the mole ratio of CH4 and H2; it can be on these form and use the appropriate ratio depending on your desired unit;

1molCH42molH2

or

2molH21molCH4

Once known, multiply the value to the mole of CH4 as provided in the problem to find the mole of H2;

0.6 mol CH4 x## ?

Then, find the molar mass of H2 to use to find the mass of H2 needed to produce CH4.

The answer is 2.4 grams of H2
