Question 1

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 114.33 g mol-1. The molar mass of carbon dioxide is 44.0095 g mol-1.

2C8H18 + 25O2 → 16CO2 + 18H2ODrH° = -11018 kJ

◦ 18.18 moles
◦ 10.93 moles
◦ 14.00 moles
◦ 6.997 moles
◦ 8.000 moles

Question 2

Using the following equation for the combustion of octane, calculate the amount of moles of oxygen that reacts with 100.0 g of octane. The molar mass of octane is 114.33 g mol-1. The molar mass of carbon dioxide is 44.0095 g mol-1.

2C8H18 + 25O2 → 16CO2 + 18H2ODrH° = -11018 kJ

◦ 6.997 moles
◦ 10.93 moles
◦ 8.000 moles
◦ 18.18 moles
◦ 14.00 moles
