One compartment in a gasoline tank truck has a volume of 11,860 liters.

a. How much gasoline liquid (in liters) is required to result in a stoichiometric concentration of gasoline vapor in this compartment?

b. What is the TNT equivalence of this gasoline vapor, based on a confined explosion?

Assume \(1 \mathrm{~atm}\) and \(25^{\circ} \mathrm{C}\) ambient conditions.

Assume that the gasoline is mostly octane \(\left(\mathrm{C}_{8} \mathrm{H}_{18}ight)\) and has the following properties:

Molecular weight of gasoline vapor: 72 Gasoline liquid specific gravity: 0.72 Lower heating value of gasoline: \(44 \mathrm{MJ} / \mathrm{kg}\)
