a. 30 moles of H₂O

b. 2.33 moles of N₂

Further explanation

Given

a. 20 moles of NH₃

b. 3.5 moles of O₂

Required

a. moles of H₂O

b. moles of N₂

Solution

Reaction

4NH₃+3O₂⇒2N₂+6H₂O

a. From the equation, mol ratio NH₃ : H₂O = 4 : 6, so mol H₂O :

=6/4 x mol NH₃

= 6/4 x 20 moles

= 30 moles

b. From the equation, mol ratio N₂ : O₂ = 2 : 3, so mol N₂ :

=2/3 x mol O₂

= 2/3 x 3.5 moles

= 2.33 moles

The moles of H₂O produced by 20 moles of NH₃ are 30 moles, moles of N₂ produced by 3.5 moles of O₂ is 2.3 moles.

What is moles?

Moles is a unit of mass, which gives information about the relative amount of species present in any reaction.

Given chemical reaction will be represented as:
4NH₃ + 3O₂ → 2N₂ + 6H₂O

From the stoichiometry of the reaction it is clear that-

4 moles of NH₃ = produce 6 moles of H₂O

20 moles of NH₃ = produce 6/4×20=30 moles of H₂O

Again from the stoichiometry of the reaction it is clear that-

3 moles of O₂ = produce 2 moles of N₂

3.5 moles of O₂ = produce 2/3×3.5=2.3 moles of N₂

Hence required moles are 30 moles of H₂O and 2.3 moles of N₂.
