Answer:
Average atomic mass of potassium based on these relative abundances
Explanation:
The atomic mass of this element will be equal to the sum of product of its three isotopic masses and its fractional abundance
For isotope I -
Mass of Potassium-39 amu
Fractional abundance of Potassium-39 %
Mass of Potassium-40 amu
Fractional abundance of Potassium-40 %
Mass of Potassium-41 amu
Fractional abundance of Potassium-41 %
Average atomic mass of potassium based on these relative abundances
