1. Calculate the amount of moles of octane:
n = m/M = 100.0 g/114.33 g/mol = 0.874 mol

2. Use the stoichiometric coefficients of octane and carbon dioxide to calculate the amount of moles of carbon dioxide produced:
n_CO2 = 16 mol CO2/2 mol C8H18 x 0.874 mol C8H18 = 6.997 mol CO2

3. Use the molar mass of carbon dioxide to convert moles to grams if needed.
