Consider the reaction below.
2c6h14 + 190212c02 + 14h20
how many moles of hexane (c6h14) must burn to form 18.4 mol of carbon dioxide?
1.53 mol
3.07 mol
110. mol
175. mol

B. 3.07 moles

Explanation:

For every 2 moles of C6H14, 12 moles of C02 are produced.

So for every 1 mole of C6H14, 6 moles of CO2 are produced.

1:6 ratio

You can set it up as fractions, makes the problem a lot easier.

1 =  ?

6   184

cross multiply and solve!

3.07 moles
