Calculate the volume of co2 when a tank of petrol(32kg) undergoes complete combustion (1mole of gas occupies 24dm3)?

Petrol is predominantly made up of octane (written as C8H18) so... The equation for the complete combustion of octane is: 2C8H18 + 25O2 ——-> 18H20 + 16CO2 2 Octane molecules + 25 oxygen molecules ———-> 18 water molecules + 16 carbon dioxide molecules. Octane has a relative formula mass of 384 32kg= 32,000g 32,000g / 384 = 83.33 moles of octane There are 8 times as many moles of carbon dioxide as there is octane so... 83.33 x 8 = 666.4 666.4 moles x 24dm3 per mole = 15,999.36 dm3 occupies Answer: 15,999.36 dm3
