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.

Match the characteristic of gases described below to the postulates of the kinetic molecular theory that best explain that characteristic. (Note: You may need to list more than one postulate.)
