Question

Ethanol is the active ingredient of alcoholic beverages. It is also s a possible replacement for gasoline. The complete combustion of ethanol forms carbon dioxide and water.

CH3CH2OH + O2 => CO2 + H2O

Balance the equation. What mass of carbon dioxide is formed by the complete combustion of 775 g of ethanol?
CH3CH2OH + 3O2 => 2CO2 + 3H2O

CH3CH2OH is
2*C = 24 +
6*H = 6 +
1*O = 16 = 46 grams/mol

so that is 775/46 = 16.85 mols of ethanol
so we would get 2*16.85 = 33.7 mols of CO2
CO2 = 12+32 = 44 grams/mol
33.7 *44 = 1483 grams of CO2
Oh my, greenhouse galore
