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