Each molecule of hydrogen gas (h 2 ) is made of two hydrogen atoms. if you have 6.022 * 10 ^ 23 molecules of hydrogen gas, then how many moles of hydrogen atoms do you have?

one mole of hydrogen gas will have 6.022 × 10²³ molecules.

Explanation:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

For example,

18 g of water = 1 mole = 6.022 × 10²³ molecules of water

1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen

2 g of H₂ = 1 mole = 6.022 × 10²³ molecules of H₂
