How to find the relative atomic mass of chlorine?

The relative atomic mass of chlorine is 35.5. Chlorine is an element with one valence electron, which means it has one electron in its outer shell. Chlorine has an atomic number of 17, so its relative atomic mass is 17 × 35.5, which equals 589. That equals the mass of 17 protons, 17 neutrons, and 17 electrons.

How to find the chlorine atomic mass?

Chlorine has two different isotopes: 35Cl and 37cl The relative atomic mass of 35Cl is 35.5 and of 37Cl is 37.5. This gives a relative atomic mass of 35.5% for 35Cl and 65.5% for 37Cl.

How to calculate the relative atomic mass of chlorine?

The relative atomic mass of an element, denoted by the symbol “m” (or sometimes “u” for unified atomic mass unit), is the ratio of the mass of an atom of that element to the mass of a single atom of the most common isotope of the element. The relative atomic mass is usually expressed in daltons.

How to find the mass of chlorine atoms?

If you know the average mass of a proton, you can find the relative atomic mass of chlorine using the following formula:

How to calculate the relative molecular mass of a substance containing chlorine?

The relative atomic mass of chlorine is always equal to the relative molecular mass of the chlorine atom multiplied by the number of atoms in your sample.
