Question

What is the correct formula for the calculation of the average atomic mass of an element with two isotopes? Average atomic mass = AAM

Answer 1

Answer:

hey

Explanation:

Average atomic mass = X .A + Y.B/X+Y

where x and y are % of isotopes

Answer 2

Answer:atomic mass of isotopes

Explanation:

For example-..carbon has three isotopes..c12,c12,c14..with (relatice abundance and masses)...RELATIVE ABUNDANCE OF C12-98.892% and MASS-12...so we have to mutiply relative abundance with mass.....so 98.892×12=1186.704...
