### How many moles are in KCl?

One mol of KCl is equal to 74.6 grams (from the periodic chart, the gram-atomic mass of potassium is 39.0 and that of chlorine is 35.5. Add together for the gram-molecular mass of 74.6). If you took 74.6 grams of KCl and diluted this to one liter with water, you would have a 1.00 M KCl solution.

## What is the mass of 6.02 x10 23 potassium atoms?

39.1 g
In your case, 6.02⋅1023 atoms of potassium will be equivalent to one mole of potassium. Here is where the cool part comes in. Therefore, you can say that one mole of potassium has a mass of 39.1 g .

## How is atomic weight calculated?

The atomic weight of any atom can be found by multiplying the abundance of an isotope of an element by the atomic mass of the element and then adding the results together. This equation can be used with elements with two or more isotopes: Carbon-12: 0.9889 x 12.0000 = 11.8668.

How do we find the atomic mass of an element?

For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit (amu). By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom.

### What is the formula for calculating molar mass?

Molar Mass is the mass of one mole of a substance (6.02 x 10 23 formula units). The unit for molar mass (note it is the mass of a mole) is grams/mole.

### What is the empirical formula of KCl?

The chemical formula for an ionic compound such as KCl is always the same as its empirical formula. We can determine the empirical formula for potassium chloride by using the charges on the ions. Potassium ions have a 1+ charge, and the formula K+, and chloride ions have a 1− charge, and the formula Cl−.

Is KCl a molecular formula?

Potassium chloride is a metal halide having the chemical formula KCl. It is an odorless, white crystalline powder. It readily dissolves in water, creating a salt-like taste. It has many uses such as in fertilizers, explosives, scientific applications, food processing, etc. KCl is produced from minerals such as potash.

## What is the density of KCl?

The density of the chemical compound potassium chloride is 1.98 grams per cubic centimeter
