Question

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

Answer 1

B, 3.07

Answer 2

no of moles of C6H14 required would be 3.07

Step-by-step explanation:

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

1 mole of C6H14 would give
`(12)/(2)=6` 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
