have three moles of Methane (CH) on the reactant side of the reaction. Do I have enough information to determine how many moles of products I will have following a reaction? If not, what else do I need to know?

No, you do not have enough information to determine how many moles of products you will have following the reaction. To determine the stoichiometry of a reaction and predict the number of moles of products, you would need the balanced chemical equation for the reaction. This equation specifies the molar ratios between the reactants and products. Without it, you cannot accurately calculate the amount of products formed.
