The number of hydrogen atoms present in one mole of hydrogen molecule is:
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
