How many liters of hydrogen gas can be produced if 102 grams of methane gas (CH4) are combusted at 315 K and 1.2 atm? Show all of the work used to solve this problem.

Without arrows you don't know the difference between reactants and products.
Here is a site that explains stoichiometry problems with a worked example.
You will need to find moles; use PV = nRT and use the conditions cited in the problem.
