The two isotopes of potassium with significant abundance in nature are 39K (isotopic mass 38.9637 amu, 93.258%) and 41K (isotopic 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.

Step-by-Step Solution:

Solution 96P

Here, we have to calculate the formula mass of potassium fluoride.

Step 1 of 3

The given two isotopes are and

Let’s calculate the proton atomic mass from two isotopes.

For

Given

Isotopic mass = 38.9637 amu

Abundance = 93.258%

Calculate the fraction value =  = 0.93258.

Proton of atomic mass from   = Isotopic mass x Abundance

=  38.9637 x  0.93258

=  36.337 amu

Therefore, Proton of atomic mass from  is 36.337 amu.

For

Given

Isotopic mass = 40.9618 amu

Abundance = 6.730%

Calculate the fraction value =  = 0.06730

Poton of atomic from  =  Isotopic mass x Abundance

= 40.9618 x 0.06730

= 2.757 amu.

Therefore, proton of atomic mass from   is 2.757 amu.
