A car uses 114 g of petrol to travel one mile.
Calculate the mass of carbon dioxide produced when this car travels one mile.
352g
I will assume petrol is octane although that isn't quite correct.
2C8H18 + 25O2 ==> 16CO2 + 18H2O
mols petrol = grams/molar mass
mols CO2 poduced = mols C8H18 x (16 mols CO2/2 mols C8H18) = ?
Then g CO2 = mols CO2 x molar mass CO2.
352
To calculate the mass of carbon dioxide (CO2) produced when the car travels one mile, we need to know the carbon content per gram of petrol.
The carbon content of petrol can vary, but on average, it is approximately 86% carbon. This means that for every gram of petrol burned, 0.86 grams of carbon dioxide is produced.
Now, let's calculate the mass of carbon dioxide produced when the car travels one mile:
1. Convert the petrol consumption from grams per mile to kilograms per mile:
114 g = 0.114 kg (since 1 kg = 1000 g)
2. Calculate the mass of carbon dioxide produced:
Mass of CO2 = Mass of petrol x Carbon content of petrol
Mass of CO2 = 0.114 kg x 0.86
Mass of CO2 = 0.09804 kg
Therefore, when the car travels one mile, it produces approximately 0.09804 kg (or 98.04 grams) of carbon dioxide.
