Hey there! As a supplier of Ferrous Sulphate, I often get asked about its molar mass. So, let's dive right into it and break down what the molar mass of Ferrous Sulphate is all about.
First off, Ferrous Sulphate can exist in different forms, mainly Ferrous Sulphate Monohydrate and Ferrous Sulphate Heptahydrate. These different forms have different molar masses due to the varying number of water molecules associated with the compound.
Let's start with the basic chemical formula of Ferrous Sulphate. Ferrous Sulphate has the chemical formula FeSO₄. To calculate the molar mass of FeSO₄, we need to know the atomic masses of the elements involved. The atomic mass of iron (Fe) is approximately 55.845 g/mol, the atomic mass of sulfur (S) is about 32.065 g/mol, and the atomic mass of oxygen (O) is around 15.999 g/mol.
For FeSO₄, we have one iron atom, one sulfur atom, and four oxygen atoms. So, the molar mass of FeSO₄ is calculated as follows:
Molar mass of FeSO₄ = (1 × atomic mass of Fe) + (1 × atomic mass of S) + (4 × atomic mass of O)
= (1 × 55.845 g/mol) + (1 × 32.065 g/mol) + (4 × 15.999 g/mol)
= 55.845 g/mol + 32.065 g/mol + 63.996 g/mol
= 151.906 g/mol
Now, let's talk about the different hydrates of Ferrous Sulphate.
Ferrous Sulphate Monohydrate
Ferrous Sulphate Monohydrate has the chemical formula FeSO₄·H₂O. This means that for every one molecule of FeSO₄, there is one molecule of water (H₂O) associated with it. The molar mass of water (H₂O) is calculated as (2 × atomic mass of H) + (1 × atomic mass of O). The atomic mass of hydrogen (H) is approximately 1.008 g/mol. So, the molar mass of H₂O is (2 × 1.008 g/mol) + (1 × 15.999 g/mol) = 2.016 g/mol + 15.999 g/mol = 18.015 g/mol.
To find the molar mass of Ferrous Sulphate Monohydrate, we add the molar mass of FeSO₄ and the molar mass of one water molecule.
Molar mass of FeSO₄·H₂O = molar mass of FeSO₄ + molar mass of H₂O
= 151.906 g/mol + 18.015 g/mol
= 169.921 g/mol

Ferrous Sulphate Heptahydrate
Ferrous Sulphate Heptahydrate has the chemical formula FeSO₄·7H₂O. This indicates that for every one molecule of FeSO₄, there are seven molecules of water associated with it.
To calculate the molar mass of Ferrous Sulphate Heptahydrate, we add the molar mass of FeSO₄ and the molar mass of seven water molecules.
Molar mass of FeSO₄·7H₂O = molar mass of FeSO₄ + (7 × molar mass of H₂O)
= 151.906 g/mol + (7 × 18.015 g/mol)
= 151.906 g/mol + 126.105 g/mol
= 278.011 g/mol
