So we have four hydrogens here. Again the amount of product produced, in this case methanol, is limited by the amount of limiting reactant we have since the reaction cannot proceed if we have no more carbon monoxide. Based on the mole ratios, what can most likely be predicted? And then you can compare how much of the reactants you'd need to how much of the reactants you actually have to determine the limiting reactant. And so this is going to Technically we should only round off our numbers at the very last calculation or else we could invite error into our final answer.
