3.13

4.44.5

5.82

Answer 2

Answer:

$\sf Atomicity \ of \ Argon = 1\\\sf Atomicity \ of \ chlorine = 2\\\sf Atomicity \ of Aluminium = 1\\\sf Atomicity \ of \ Phosphorous = 4\\\sf Atomicity \ of \ Sulphur = 8$

Explanation:

Atomicity  is the ratio of the molecular mass and atomic mass .

1. Atomicity of Argon

We know that ,

Argon is an inert gas and the atomicity of all inert gases are 1

2. Atomicity of Chlorine  

We know that Chlorine exists as Cl₂

Atomic mass of Chlorine = 35.5 u

Molecular mass of Chlorine = 35.5 × 2 = 71 u

Atomicity = Molecular mass

                    Atomic mass

               = 71/35.5 = 2

3.Atomicity of Aluminium

Since Alluminium exists as Al

Atomicity = 1

4.Atomicity of Phosphorus

Phosphorpus exists as P4

Atomicity = 4

5.Atomicity of Sulphur

Sulphur exists as S₈

Atomicity of sulphur = 8
