Answer:

Mass = 61.6 g

Explanation:

Given data:

Mass of ammonia produced = 75.0 g

Mass of nitrogen needed = ?

Solution:

Chemical equation:

N₂ + 3H₂    →      2NH₃

Number of moles of ammonia:

Number of moles = mass/molar mass

Number of moles = 75 g/ 17 g/mol

Number of moles =  4.4 mol

No we will compare the moles of ammonia with nitrogen.

              NH₃           :          N₂

                2             :           1

               4.4           :          1/2×4.4 =2.2 mol

Mass of N₂:

Mass = number of moles × molar mass

Mass = 2.2 mol × 28 g/mol

Mass = 61.6 g
