Radon (222 g/mol) is a naturally occurring radioactive gas found in the ground and in building materials. It is easily inhaled and emits alpha particles when it decays. Cumulative radon exposure is a significant risk factor for lung cancer. Calculate the density of radon at 317 K and 1.00 atm of pressure.

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.
