Question

If a car produces 88 grams of co2 how many grams of o is used up in the reactionin c2h6o o2

Answer 1

B. (4.0 mol C2H6O) x (3/1) = 12 mol O2

C. Supposing all the C in the CO2 came from ethanol:
(88 g CO2) / (44.00964 g CO2/mol) x (3/2) x (31.99886 g O2/mol) = 96 g O2

D. (125 g C2H6O) / (46.06867 g C2H6O/ mol) x (2/1) x (44.00964 g CO2/mol) =
239 g CO2

(125 g C2H6O) / (46.06867 g C2H6O/ mol) x (3/1) x (18.01532 g H2O/mol) =
