Using this equation: CH4(g)+2O2(g)---> CO2(g)+ 2H2O(l)

What is the value of Enthalpy( triangle H) if 15.00g of O2 is reacted??

How do i set up the mole to mole ration?? with what am i comparing it too??

Make sure the equation is balanced. Is this for "so-called" standard conditions? If so, go the tables in your text and look up delta Hfo values.
delta H rxn = (delta H products) - (delta H reactants). That will give you the delta H for the reaction for 64 g oxygen. Set up a proportion to find delta H for 15 g.
