How many grams of CO2 are formed when 32 g of O2 reacts with 23 g of C2H5OH?

    This is a limiting reagent problem. I know that because amounts are given for BOTH reactants.
    1 Write and balance the equation.
    2. Convert g O2 t mols. mols = grams/molar mass
    3. Convert g C2H5OH to moles.
    4a. Using the coefficients in the balanced equation, convert moles oxygen to moles CO2.
    4b. Same procedure, convert mols C2H5OH to moles CO2.
    4c. Both answers can't be right; the correct one in limiting reagent problems is ALWAYS the smaller value.
    5. Using the smaller value, convert moles CO2 to grams. g = moles x molar mass.
