I have a question on my homework that I can't figure out if anyone can please help me with how to do it that would be great! Here is the question:
1. Consider the reaction: CH3OH(g) = CO(g) + 2H2(g) ΔH=+90.7kJ

a) For a given sample of CH3OH, the enthalpy change is found to be 25.8kJ. How many grams of H2 gas are produced?
