The mass of hydrogen present in 50.7 grams of ammonia is equal to 8.95 g.
<h3>What is a mole?</h3>
A mole is a scientific unit that is used to determine the huge number of quantities of atoms, molecules, ions, etc. The mass of the 1 mole of any element is called atomic mass and that of one mole of any compound is called molar mass.
The number of entities present in 1 mole was found to be equal to 6.023 × 10 ²³ per mole which is known as Avogadro’s constant.
Given, the mass of ammonia = 50.7 g
The mass of the one mole of ammonia = 17 g/mol
17 g of ammonia contain the mass of hydrogen = 3 g
50.7 g of ammonia contains a mass of hydrogen = (3/17) × 50.7 = 8.95 g
