Question

Combustion of 1 mol of octane results in the formation of 8 mol of carbon dioxide (CO2) . The molar mass of octane is 114.22 g/mol, and the molar mass of carbon dioxide is 44.01 g/mol. If an engine burns 550.0 g octane as it runs, what mass of carbon dioxide is released into the atmosphere?

Answer 1

mols C8H18 = grams/molar mass
mols CO2 = 8x that
g CO2 = mols CO2 molar mass CO2

Answer 2
