Problem

Using the following equation for the combustion of octane, calculate the amount of moles of carbon dioxide formed from 100.0 g of octane. The molar mass of octane is 114.22 g/mol. The molar mass of carbon dioxide is 44.01 g/mol.

a. 6.997 moles

b. 8.000 moles

c. 10.93 moles

d. 18.18 moles

e. 14.00 moles

Solution

Given:

• mass octane (C8H18) = 100 g
• molar mass octane (C8H18) = 114.22 g/mol
• molar mass carbon dioxide (CO2) = 44.01 g/mol  (extra information, not needed)
