The molecular mass of CuSO4. 5H2O is 249.5 gm/mole. The molecular mass of a compound is the sum of the atomic masses of all the constituent molecules.

We know that:

The atomic mass of H = 1g
The atomic mass of O = 16g
The atomic mass of Cu = 63.5g
The atomic mass of S = 32g

The molecular mass of CuSO4. 5H2O = Atomic mass of Cu + Atomic mass of S + (9 x atomic mass of O) + (10 x atomic mass of H)

Substituting the values we get:

= 63.5 + 32 + 9 x 16 + 10 x 1

= 249.5 gm/mole

Hence, the molecular mass of CuSO4. 5H2O is 249.5 gm/mole.

Uses of copper sulfate

The pentahydrate of this substance is CuSO4. 5H2O is used as a fungicide since a variety of fungi can be killed by it.
Copper sulphate is a component of both Fehling’s solution and Benedict’s solution, which are tests for reducing sugars.
Using this technique, blood samples are checked for diseases like anaemia.
The oxidant produced by the combination of KMnO4 (potassium permanganate) and CuSO4 can be utilised to convert 1o
When utilising vegetable dyes, it also acts as a fixative for the colour.
By dissolving copper sulphate in water, liquid resistors containing resistive elements can be created.
It can be used as a decorative element because it can also give cement, ceramics, and other metals colour.
Bookbinding glues also contain copper sulphate, which protects printed paper from insects.
