34 grams of carbon is approx. 2.833 moles (because molar mass of carbon is 12 grams). Since there is unlimited water, Carbon is the limiting reagent, so taking into account that the equation is already balanced and the fact that in the balanced equation the mole ratio between carbon and Hydrogen gas is 1 to 1, there are 2.833 moles of hydrogen, multiply that by the molecular mass of the Hydrogen gas you get 5.71 grams of Hydrogen gas.
