The van der Waals equation, nRT = [P + (n/V)2a)](v-nb) incorporates corrections to the ideal gas law in order to account for the properties of real gases. One of the corrections accounts for     the quantum behavior of molecules.     that average kinetic energy is inversely proportional to temperature.     the finite volume of molecules.     the possibility of chemical reaction between molecules.

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.
