Question

How many moles of carbon dioxide gas can be produced when 9.36 moles of benzene (C6H6) react with excess oxygen?
Be sure to show the work that you did to solve this problem.
Unbalanced equation: C6H6 + O2 ---> CO2 + H2O

Answer 1

First write balanced equation:
C6H6 + (15/2) O2 ---> 6 CO2 + 3 H2O CO2 is produced in a 6:1 ratio with the consumption of C6H6 
So 9.36 moles C6H6 should produce 9.36 x 6 = 56.16 moles CO2
