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

the answer is 3.07

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.
