Three elements X, Y and Z follow Doberin...

Three elements X, Y and Z follow Doberiner's law of traids. If atomic masses of X and Z are 7 and 39 respectively, then determine the atomic mass of Y.

Text Solution

Verified by Experts

Atomic mass of Y=arithmatic mean of atomic masses of X and Z. therefore, atomic mass of Y=7+39/2=23.
