the atomic mass of potassium is approximately 39
39.0983
Atomic mass is so small you can't actually measure it. So, just like carbon dating, you have to use a relative mass.
39.0983
Sodium is a meta element. Atomic mass of it is 23.
It is 38.96
It is 39.10
The atomic mass of potassium is 39.0893
Since potassium chloride has the formula KCl and the mass of the lost electron from neutral potassium is negligible compared with the mass of the protons and neutrons in the potassium atom nucleus, the molecular mass of potassium in this compound is the same as the atomic mass of potassium, 39.098.
The atomic number is 19 and the mass number of its most abundant isotope K-39 is 39 (19 protons + 20 neutrons) while the mass of that isotope is 38.96371 a.m.u.The relative atomic mass of the element potassium, K, is 39.10 g/mole.
