Question

What is the molar mass of iron?

Answer 1

Hint: Iron is an element that belongs to the d-block because the last electron enters the d-orbital of the 3rd shell. It is the element of period number 4 and group number 8, and the atomic number of the iron element is 26.

Complete answer:
When we calculate the mass of one mole of a particular substance or element is known as the molar mass of that substance or element. We can also define the molar mass of a substance as the number of grams per mole of a substance. We know that in one mole of a substance there are a large number of atoms or molecules of that specific compound and the total mass of all the atoms or molecules is known as molar mass.
So, we have to find the mass of iron. We know that iron is an element that belongs to the d-block because the last electron enters the d-orbital of the 3rd shell. It is the element of period number 4 and group number 8, and the atomic number of the iron element is 26.
So, the atomic mass or molar mass of iron will be the same and it is equal to 55.845 g/ mol.
Iron is a metal, and there are many properties of iron like lustrous, ductile, malleable, etc which makes it very useful in many applications. In the universe, it is the 10th most abundant element.

Note:
Some properties of iron are, it dissolves in dilute acids, it gets rusted easily when it comes in contact with air and water, it has a very good property of magnetism and it has good electrical properties also.
