A mole of any substance contains Avogadro's number of particles, which is approximately 6.022 x 10^23. Therefore, a mole of hydrogen gas (H2) contains approximately 6.022 x 10^23 molecules of H2.

However, because each molecule of hydrogen gas is diatomic (H2), meaning it is composed of two hydrogen atoms, a mole of hydrogen gas actually contains approximately 2 x 6.022 x 10^23, or 1.2044 x 10^24, hydrogen atoms.
