Number of moles : n₂ = 1.775 moles
<h3>Further explanation</h3>Given
Moles = n₁ = 1.4
Volume = V₁=22.4 L
V₂=28.4 L
Required
Moles-n₂
Solution
Avogadro's hypothesis, at the same temperature and pressure, the ratio of gas volume will be equal to the ratio of gas moles
The ratio of gas volume will be equal to the ratio of gas moles
Input the values :
n₂ = (V₂ x n₁)/V₁
n₂ = (28.4 x 1.4)/22.4
n₂ = 1.775 moles
Answer:
396811.337 J
Explanation:
The cost of one short ton of coal = $56.45
The energy related to the short ton of coal =
Thus, As according to the question,
$56.45 of coal have of energy.
$1 of coal have of energy.
<u>The amount of energy = 396811.337 J</u>
