Chlorine naturally occurs with mixed isotopes, and the number is an average of the Atomic Mass of those isotopes, in the proportion they are present.

The isotopes have the same atomic number (protons), but their mass number can be different due to the presence of a different number of neutrons. These atoms of an element having a different number of neutrons are called isotopes.
