The elements chlorine exists from two isotopes: 35Cl or 37Cl. m(35Cl) = 34.969 u, frequency = 75.77%, m(37Cl) = 36.966 u.
Calculate the average mass of a chlorate atom and interpret the result.
Solution: m(Cl) = 0.7577·34.969 u + (1-0.7577)·36.966 u = 35.4528731 u
The average mass of a hydrochloric acid is 35.4528 u or A Mol would have the mass of 35.4528 grams. Note: even if you search so well in nature, you will never find such an atom. Either the chloratomes have a mass of 34.969 u or a mass of 36.966 u.
