What is the volume of carbon monoxide (IV), formed during the combustion of hexane, weighing 500 grams, if the mass of incombustible impurities in the hexane sample is 8%?
The combustion reaction of hexane is as follows:
2C6H14 + 19O2 = 12CO2 + 14H2O.
Pure hexane reacts in the amount of:
((100% – 8%): 100%) * 500 g: 86 g / mol = 5.35 mol.
Carbon dioxide is obtained by volume:
5.35 mol * 1/6 * 22.4 l / mol = 20 l.
