Calculate the molecular mass of CuSO4. 5H2O

By Ritesh|Updated : November 14th, 2022

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.

Summary:

Calculate the molecular mass of CuSO4. 5H2O

The molecular mass of CuSO4. 5H2O is 249.5 gm/mole. Both hydrated and anhydrous copper sulphates have a tendency to break down when heated, so they lack precise boiling points. Blue, hydrated copper(II) sulphate is a solid that is bound to water molecules.
