Question

What is the atomic mass of K?

Answer 1

Hint : We know that each particle of matter has some measure of mass related to it, whether little or huge. Everything is composed of atoms. Mass of an atomic particle is known as the atomic mass. This is usually expressed according to the international arrangement as far as a brought together atomic mass unit (amu).

Complete Step By Step Answer:
The atomic weight of an atom is a dimensionless number when it is isolated by bound together atomic weight or Daltons. This is known as the total isotopic mass. The atomic masses of elements change from 1.008 amu for hydrogen up to $250$ amu for elements which have an extremely high atomic number. Mass of molecules can be dictated by including the normal atomic mass of every atom in the molecule. In this article, we will learn about atomic mass and molecular mass, what is the atomic mass of iron, what is the atomic mass of potassium, and learn in general about the atomic and molecular masses.
By definition the molar mass of potassium $(K)$ equals its atomic mass in grams. Hence, the calculation of the molar mass of potassium is needed. The molecular mass (also called as formula mass) of a compound refers to the total of the atomic masses of the apparent multitude of atoms in the molecule. Here we have given only potassium thus we will consider atomic mass for one mole.
$1K=1\times 39.0983u$ here $39.0983u$ is predefined mass for potassium.
Suppose we have to calculate atomic mass for two mole of potassium.
$1K=2\times 39.0983u=78.1966u$

Note :
Remember that most of the things that we study in chemistry depend on the proportions of the atoms. The atomic mass number refers to the total number of nucleons, which are the total number of both protons and neutrons together, in the atomic nucleus. It is denoted by the symbol A and is also called as the nucleon number.
