In the HCI molecule, the separation between the nuclei of the two atoms is about 1.27 Å (1Å =10^(10)m) . Find the approximate location of the CM of the molecule, given that the chlorine atom is about 35.5 times as massive as a hydrogen atom and nearly all the mass of an atom is concentrated in all its nucleus.

Calculate the average atomic mass of chlorine if no distinction is made between its different isotopes?
