It's absolutely crucial that you are able to write out a BALANCED chemical equation. You have: $H_{2(g)} + CS_{2(l)} \rightarrow CH_{4(g)}+H_2S_{(g)}$ I'll leave it to you to balance the equation. From the equation, "n" mole H2 is equivalent to 1 mole CH4 22.4 L (at STP) of CH4 is produced from "n"x22.4 L of H2 Hence, _____ L of CH4 will be produced from "n" x ____ L = 1 Thats how you solve. in this case "n" represents mole (which you should be able to get after you balance the chemical equation I gave you).
