Answer:
Average atomic mass = 63.62 amu.
Explanation:
Abundance of Co⁶³ = 69.2%
Abundance of Co⁶⁵ = 30.8%
Atomic mass of Co⁶³ = 63 amu
Atomic mass of Co⁶⁵ = 65 amu
Average atomic mass = ?
Solution:
Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) / 100
Average atomic mass = (63×69.2)+(65×30.8) /100
Average atomic mass = 4359.6 + 2002 / 100
Average atomic mass = 6361.6 / 100
Average atomic mass = 63.62 amu.
