How many kg of CO2 are emitted from an automobile that completely combusts all the gasoline in its 16.5 gallon fuel tank? You may assume that gasoline is entirely octane, which has the following combustion equation: 2 C3H18 () + 25 O2 (g) → 16 CO2 (g) + 18 H2O (g) Useful information: 1 gallon = 3.7854 L. %3! • This combustion occurs in excess O2. • The density of octane is p = 703 g/L. • The molar mass of CO2 is 44.01 g/mol. • The molar mass of octane is 114.23 g/mol.

How many kg of CO2 are emitted from an automobile that completely combusts all the gasoline in its
16.5 gallon fuel tank? You may assume that gasoline is entirely octane, which has the following
combustion equation:
2 C3H18 (1) + 25 O2 (g) → 16 CO2 (g) + 18 H2O (g)
Useful information:
1 gallon = 3.7854 L.
• This combustion occurs in excess O2.
The density of octane is p = 703 g/L.
• The molar mass of CO2 is 44.01 g/mol.
• The molar mass of octane is 114.23 g/mol.
