Answer:
Average atomic mass of potassium based on these relative abundances
![= 39.0944](https://tex.z-dn.net/?f=%3D%2039.0944)
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
![= (38.9636 * 0.9326)+ (39.9640*0.0001) + (40.9618 * 0.0673)\\= 36.3374 + 0.0003 + 2.7567\\= 39.0944](https://tex.z-dn.net/?f=%3D%20%2838.9636%20%2A%200.9326%29%2B%20%2839.9640%2A0.0001%29%20%2B%20%2840.9618%20%2A%200.0673%29%5C%5C%3D%2036.3374%20%2B%200.0003%20%2B%202.7567%5C%5C%3D%2039.0944)
