The two isotopes of potassium with significant abundance in nature are 39k asotopic mass 38.9637 amu, 932.58%) and 41k osotopic mass 40.9618 amu, 6.730%). fluorine has only one naturally occurring isotope, 19f (isotopic mass 18.9984 amu). calculate the formula mass of potassium fluoride.

Explanation:

1. Atomic mass of K

To get the atomic mass of K, you calculate the weighted average of the isotopic masses.

That is, you multiply the atomic mass of each isotope by a number representing its relative importance (e.g., its percent of the total).

Set up a table for easy calculation:

2. Formula mass of KF
