Question

The chemical equation below represents the formation of ammonia.

N2 + 3 H2 --> 2 NH3

How many grams of ammonia are produced when 1.0 mole of nitrogen reacts?

Answer 1

Answer:

Mass of ammonia produced= 34 g            

Explanation:

Given data:

Mass of ammonia produced = ?

Number of moles of nitrogen = 1.0 mol

Solution:

Chemical equation:

N₂ + 3H₂       →    2NH₃

Now we will compare the moles of ammonia and nitrogen.

                   N₂          :          NH₃

                    1           :           2

Mass of ammonia:

Mass = number of moles × molar mass

Mass =    2 mol × 17 g/mol

Mass = 34 g
