Moles of H₂ are needed to produce 9.33 moles of NH₃ : 13.995
<h3>Further explanation</h3>
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
The reaction coefficient in a chemical equation shows the mole ratio of the reactants and products
Reaction for the synthesis of ammonia :
N₂+3H₂⇒2NH₃
moles of NH₃ = 9.33
From equation, mol ratio of H₂ : NH₃ = 3 : 2, so mol H₂ :
Answer:
4 M
Explanation:
Molarity can be represented by the following ratio:
Molarity = moles / volume (L)
Since you have been given both the mass and volume, you can plug the values into the equation and solve for molarity.
Molarity = moles / volumes
Molarity = 2.0 moles / 0.50 L
Molarity = 4 M
