Consider the reaction below.

2c6h14+ 1902 12co2 +
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

no of moles of C6H14 required would be 3.07

Explanation:

from the equation below we can see that 2 moles of C6H14 gives 12 moles of C02.

 1 mole of C6H14 would give moles of CO2.

let the amount of C6H14 required to obtain 18.4 moles of CO2 be x

therefore x moles of C6H14  would produce 6x moles of CO2.

given 6x = 18.4

therefore x = 3.07 moles
