## What is the mass of one atom of K?

39.10 g/mol.

Referring to the periodic table, the atomic mass of K is 39.10 amu, and so its molar mass is 39.10 g/mol.

## What is K in mass?

Potassium is a chemical element with symbol K and atomic number 19. The Atomic mass of Potassium is 39.0983. To calculate Molar Mass, multiply the number of atoms of the element by Atomic mass. 1 x 39.0983. Therefore, the Molar Mass of Potassium is 39.0983 g/mol.

**What is the atomic mass of K 39?**

38.963707

Potassium-39 atom is the stable isotope of potassium with relative atomic mass 38.963707, 93.3 atom percent natural abundance and nuclear spin 3/2.

**What are the grams of K?**

Potassium is a chemical element that you can find in the periodic table. The symbol for potassium is K, and its atomic number is 19. More importantly for the purposes of making our converter, the atomic mass of potassium is 39.0983. That means that one mole of potassium weighs 39.0983 grams (39.0983 g/mol).

### What is the atomic number of K?

19

Potassium/Atomic number

### How many neutrons are in K?

20 neutrons

The element of potassium has the symbol K. The nucleus of an atom of potassium contains 19 protons and 20 neutrons.

**What is K type mass transfer coefficient?**

k is defined as the mass transfer coefficient. in this situation, based on a concentration driving force. It is possible to define a mass transfer coefficient in the same situation using a mole fraction driving force.

**What is J in mass transfer?**

j1 = diffusive molar mass flux, mol/cm2-s (Note — a flux is a rate per unit area, so the statement in Cussler that j1 is a “flux per unit area” is semantically flawed.) n1 = total molar or mass transfer rate relative to stationary coordinates. v = mass average velocity of fluid.
