Question

Calculate the average atomic mass of funnium. One isotopes of funnium has an atomic mass of 78.92 u and a relative abundance of 50.69%. The other major isotope of funnium has an atomic mass of 80.92u

Answer 1

89.17 u.

Step-by-step explanation:

he average atomic mass of funnium can be calculated as follows:

Atomic mass = (Relative abundance of first isotope * atomic mass of first isotope) + (Relative abundance of second isotope * atomic mass of second isotope)

Atomic mass = (50.69% * 78.92 u) + (100% - 50.69% * 80.92 u)

Atomic mass = 39.86 u + (49.31 u)

Atomic mass = 89.17 u

So, the average atomic mass of funnium is 89.17 u.
