Question

Find the atomicity of oxygen in
(a) KMNO4
(b) NaNO3
(c) Ca(HCO3)2
(d) CaO

Answer 1

Answer:

a aluminum sulphide

sodium sulphate

calcium oxide

carbon nitrite

Answer 2

Answer:

a) 4

b) 3

c) 6

d) 1

Explanation:

Atomicity is defined as the total number of atoms that constitute a molecule. For example, each molecule of oxygen (O2) is composed of two oxygen atoms.

Therefore,

a) Here atomicity of oxygen is 4

b) Here it is 3

c) Here it is 6 {(HCO₃)₂ = H₂C₂O₆}

d) Here it is 1
