how many moles of CO2 are produced from 2e-2 moles of C2H6O?

Question

what is the maxium mass of CO2 that can be produced by the cumbustion of _____g of ethonal how do you do this problem?

Answer 1

You may not know the mass of CO2 produced before you give the amount of ethanol combusted.
However, since one mole of C2H6O molecules contains 2 moles of C atoms, which can form 2 moles of CO2. Hence one mole of C2H6O by the combustion can produce a maximum of 2*(12+32) = 88 grams of CO2.
