Question

Which is the number of moles of carbon dioxide produced from the complete combustion of 4.3 moles of ethanol?

Answer 1

The number of moles of carbon dioxide produced will be 8.6 moles.

Stoichiometri mole ratios

First, let's look at the balanced equation of the reaction. The complete combustion of ethanol gives carbon dioxide and water as follows:

$C_2H_5OH + 3O_2 --- > 2CO_2 + 3H_2O$

We can see from the equation that the burning of 1 mole of ethanol produces 2 moles of carbon dioxide. In other words, the mole ratio is 1:2.

Thus, with 4.3 moles of ethanol, the amount, in moles, of carbon dioxide that will be produced will be:

                            4.3 x 2 = 8.6 moles

In other words, 8.6 moles of carbon dioxide will be produced from the complete combustion of 4.3 moles of ethanol.
