A sample of oxygen gas at 282 K and 0.241 atm occupies a volume of 2.37 L. If the pressure of the gas is increased, while at the same time it is cooled to a lower temperature, the final gas volume O will be larger than 2.37 L. O could be larger or smaller than 2.37 L depending on the final pressure and temperature. O will be smaller than 2.37 L.

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.
