Answer 2

Answer:

Explanation:

Concept:

Atomic mass in an atom or group of an atom is the sum of the masses of protons, neutrons and electrons.

Given:

Chlorine has a relative atomic mass of $35.5$.

Find:

What particle is a chlorine atom's mass compared to???

Solution:

Chlorine has a relative atomic mass of $35.5$ amu.

We must determine the mass of the particle to which chlorine is compared.

The IUPAC defines atomic mass as the relative mass of an element in comparison to one twelfth of the mass of the carbon 12 atom.

Alternatively, relative atomic mass = atomic mass of element $/\left(1_{/ 12} \times\right.$

The carbon $12$ atom
