Question

What is the atomic mass of chlorine and how?

Answer 1

atomic mass is 35.5 amu which is calculated by taking as average..since it occurs in isotopic dorm in nature

Answer 2

The atomic mass of chlorine is 35. Chlorine has 17 protons (which we can tell by looking at the atomic number) and 18 neutrons, which add up to give us an atomic mass of 35. On the periodic table you can find atomic weight at the bottom of the element's box. Atomic weight on the periodic table is an average of the atomic mass of all the isotopes of an element. On the periodic table, chlorine has an atomic weight of 35.453. You can see it is similar to chlorine's atomic mass.

this is ur answer.....☺️☺️☺️
