In order to compute the total hydrogen atoms present, we must first write the molecular formulas of ammonia and water to know how many hydrogen atoms are present in each molecule.

Water - H₂O; so 2 hydrogen atoms per molecule of water

Ammonia - NH₃; so 3 hydrogen atoms per molecule of ammonia

Total hydrogen atoms = 2 * molecules of water + 3 * molecules of ammonia

H atoms = 2 * 1.5 x 10²⁵ + 3 * 8.2 x 10²⁴
H atoms = 5.46 x 10²⁵

There are a total of 5.46 x 10²⁵ hydrogen atoms in the solution
