Question

Assuming the solution you used was 95% ethanol by volume and that the density of ethanol is 0.816g/mL, how much water and carbon dioxide are produced in the experiment?

Equation: C2H6O+3O2-->2CO2+3H2O

(You start off with 2.0 mL of ethanol)

Answer 1

volume ethanol that is pure ethanol is 2.00 mL x 0.95 = ? mL.
Then grams ethanol = ? mL x density = grams ethanol.
Convert g ethanol to mols. mols = grams/molar mass = ? mols ethanol.
Using the coefficients in the balanced equation, convert mols ethanol to mols CO2 and mols H2O.
Then g CO2 = mols CO2 x molar mass CO2.
g H2O = mols H2O x molar mass H2O
