C4H9OH + 6O2 ==> 4CO2 + 5H2O
mols CO2 = grams CO2/molar mass CO2.
Use the coefficients to convert mols CO2 to mols butanol.
Now convert mols butanol to grams butanol.
g = mols butanol x molar mass butanol.
mols CO2 = grams CO2/molar mass CO2.
Use the coefficients to convert mols CO2 to mols butanol.
Now convert mols butanol to grams butanol.
g = mols butanol x molar mass butanol.
