Solution

The correct option is C 12.044 x 10²³

One mole of hydrogen atoms contains 6.022x10²³ atoms.

Since there are two hydrogen atoms in a hydrogen molecule hence, one mole of H₂ molecule contains (2 x 6.022 x 10²³ = 12.044 x 10²³) atoms.
Since hydrogen molecule is diatomic hence we multiply it by 2
