Question

Atomic weight of chlorine is taken as 35.3 amu and not a whole number

Answer 1

Answer:

Explanation:

Atomic weight is weight of a atom thus it is measured in amu

1 amu = 1/N gm where N is avogadro number

So if we calculate molar mass then we get 35.3 gm

We use it as 35 but actually it is 35.3
