N2 + 3H2 mc011-1.jpg 2NH3 What is the mole ratio of hydrogen to ammonia?
2 answers:
Answer : The mole ratio of hydrogen to ammonia is, 3 : 2
Explanation :
Balanced chemical reaction : The chemical reaction in which the number of individual atoms of an element present on the reactant side always be equal to the number of individual atoms of an element present on the product side.
The given balanced chemical reaction is,
From the balanced chemical reaction, we conclude that 1 mole of gas react with 3 moles of
gas to give 2 moles of
gas as a product.
The mole ratio of nitrogen, hydrogen and ammonia is, 1 : 3 : 2
Therefore, the mole ratio of hydrogen to ammonia is, 3 : 2

Density of a substance is defined as the mass of the substance divided by the volume.
Density of the substance= 0.242 g cm⁻³
volume of the substance= 2.50 in³
As, 1 in³= 16.39 cm³
So, 2.50 in³= 16.39× 2.50 cm³=40.97 cm³
As ,
Mass=volume ×Density
Mass=40.97 × 0.242
Mass=9.916 g.
The amount of KCl that would be formed will be 478.8 grams
<h3>Stoichiometric calculations</h3>From the equation of the reaction, the mole ratio of K to is 2:1.
Mole of 309 g potassium = 309/39 = 7.92 moles
Mole of 228 g Cl2 = 228/71 = 3.21 moles
Thus, potassium is in excess while Cl2 is limiting.
Mole ratio of Cl2 and KCl = 1:2
Equivalent mole of KCl = 3.21 x 2 = 6.42 moles
Mass of 6.42 moles KCl = 6.42 x 74.55 = 478.8 grams
