Question

The atomic mass of an element is 35.5.Find the GAM?​

Answer 1

Explanation:

Chlorine in its natural state comprises two isotopes of atomic mass 35u(75%) and 37u(25%) in the ratio of 3:1.

Therefore,

Average atomic mass of chlorine =35×43+37×41=26.25+9.25=35.5u

Thus the atomic mass of chlorine is taken as 35.5u and not a whole number like 35u or 36u.

Answer 2

Answer:

Hey Mate....✨

Explanation:

ur ans is ....

For an element relative atomic mass is the average mass of the naturally occurring isotopes of that element relative to the mass of an atom of 12C. Relative atomic mass = 35.5 u....Thank you.
