How many grams of NH3 can be generated from 8.11x10^23 hydrogen atoms

Mass = 15.13 g

Explanation:

Given data:

Mass of ammonia formed = ?

Number of hydrogen atoms = 8.11× 10²³ atoms

Solution:

Chemical equation:

N₂ + 3H₂     →      2NH₃

1 mole = 6.022× 10²³ atoms

8.11× 10²³ atoms × 1 mol / 6.022× 10²³ atoms

1.35 moles of hydrogen

Now we will compare the moles of hydrogen and ammonia,

              H₂         :        NH₃

               3          :          2

              1.35      :         2/3×1.35 = 0.89

Mass of ammonia:

Mass = number of moles × molar mass

Mass = 0.89 mol × 17 g/mol

Mass = 15.13 g
