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.
