Atoms of Hydrogen =2.69x10^19 atoms
Molecules of Hydrogen (H_2) = 1.34x10^19 molecules

Explanation:

One mole of any gas occupies 22.4 Liters = 22,400 cubic cm and contains 6.02E23 particles of the substance.

Given 1 cm^3 of Hydrogen atoms (or any other gas), the number of hydrogen atoms = ("1cm"^3/(22,400cm^3))(6.02x10^23) atoms of Hydrogen = 2.69 x 10^19 atoms of Hydrogen.

For 'molecules' of hydrogen (H_2), divide the above value by 2 => (2.69x10^19)/2 = 1.34x10^19 H_2 molecules.
