Chapter 5, Problem 5.146QP

Ethanol, the alcohol used in automobile fuels, is produced by the fermentation of sugars present in plants. Corn is often used as the sugar source. The following equation represents the fermentation of glucose, the sugar in corn, by yeast to produce ethanol and carbon dioxide.

${\text{C}}_6{\text{H}}_{12}{\text{O}}_6(aq)\to 2{\text{C}}_2{\text{H}}_5\text{OH}(aq)+2{\text{CO}}_2(g)$

Ethanol is combusted in an automobile engine according to the equation

${\text{C}}_2{\text{H}}_5\text{OH}(l)+3{\text{O}}_2(g)\to 2{\text{CO}}_2(g)+3{\text{H}}_2\text{O}(g)$

What would be the total volume of CO₂ gas formed at STP when 3.00 kg of sugar is fermented and the ethanol is then combusted in an automobile engine?
