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 yields CO2 + H2O

Mercury · Answer

balanced equation: 2C6H6 + 15O2 → 12CO2 + 6H2O (let me know if you need me to derive this for you. it's not a hard process but it requires a bit of trial and error)

we start with 9.36 moles of benzene, and we want to know how many moles of carbon dioxide gas this yields. using the equation we can set up the dimensional analysis:

$$\frac{ 9.36~moles~C6H6 }{  }\frac{ 12~mol~CO2 }{ 2~mol~C6H6 }$$

perform the appropriate multiplication and division, cancelling out units as appropriate.
