Suppose we redefined the atomic mass scale by arbitrarily assigning to the naturally occurring mixture of chlorine

Question:

Suppose we redefined the atomic mass scale by arbitrarily assigning to the naturally occurring mixture of chlorine isotopes an atomic mass of 35.00000 u.

(a) What would be the atomic masses of helium, sodium, and iodine on this new atomic mass scale?

(b) Why do these three elements have nearly integral (whole-number) atomic masses based on carbon-12, but not based on naturally occurring chlorine?
