Potassium-40 is an unstable isotope with a natural abundance of 0.0117%. Therefore, in a mole of naturally occurring potassium atoms you would have 0.0117% of 6.022x10^23 atoms of K-40. Do the math: 6.022x10^23 x 0.000117
39.098 amu is the average molar mass of potassium.
The ratio is 39.098 / 12.000
Do the math.
