Which of the following is true for a gas under conditions of very low temperature? PV ÷ nRT = 1, because all gases behave ideally at very low temperatures. PV ÷ nRT = 1, because the actual volume of the gas molecules becomes considerable. PV ÷ nRT > 1, because the low temperatures speed up the particles. PV ÷ nRT < 1, because particles are unable to overcome intermolecular attractions

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.
