When looking at a compound's formula, they can become rather complicated. A simple compound might be CO2. The two capital letters tell us there are two elements. The carbon has no subscript directly to the right of it which means that, in this compound, there is only one carbon atom. The oxygen atom has a subscript of 2 which means that, in this compound, there are two oxygen atoms. How many atoms of sulfur are present in H2SO4?

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
