Gaseous substances are frequently involved in chemical reactions. If the pressure, volume, and temperature of a gas are known, the ideal gas law can be used to calculate the moles of a gas, making it possible to complete stoichiometry calculations based on the balanced chemical equation.

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.
