Consider the reaction
C6H12 + 9 O2 –> 6 CO2 + 6 H2O
How many grams of O2 are consumed when C6H12 is burned to yield 2.5 grams of CO2?
Give your answer in 1 decimal.
It said this when I got the wrong answer: Calculate the number of moles of CO2 produced in the reaction. Then match the number of moles of O2 and the corresponding number of grams of O2. Do not forget the reaction stoichiometry.
The correct answer is: 2.7
