Answer:

396811.337 J

Explanation:

The cost of one short ton of coal = $56.45

The energy related to the short ton of coal = [tex]2.24\times 10^{7}\ J[/tex]

Thus, As according to the question,

$56.45 of coal have [tex]2.24\times 10^{7}\ J[/tex] of energy.

$1 of coal have [tex]\frac{2.24\times 10^{7}}{56.45}\ J[/tex] of energy.

The amount of energy = 396811.337 J
