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
