A H2S Molecule contains 3 atoms since it is 2 atoms of H and 1atom of S.
But shouldn't it contain 1 mole of Hydrogen atoms=6.022*10^23 atoms ?

Solution

H₂S is the molecular formula of the compound.
i.e. in 1 molecule of H₂S, there are 2 atoms of H and 1 atom of S.
But in 1 mole of H₂S, there will be $2 \times 6.022 \times 10^{23}$ atoms of H and $6.022 \times 10^{23}$ atoms of S.
