The density of a gas is equal to? (P = pressure; V = volume; T = temperature, R = gas constant, n = number of moles and M = molecular wt.)
View answer and explanation
Correct option: B
PM/RT
Option B (PM/RT) is correct because the density of a gas can be derived from the ideal gas law, PV = nRT, where n = mass/molecular weight.

A quantity of hydrogen gas occupies a volume of at a certain temperature and pressure. What volume would half this mass of hydrogen occupy at triple the absolute temperature and the pressure were one-ninth that of the original gas?
In deriving the kinetic equation we make use of the root mean square speed of the molecules which is:
Consider the following statements for kinetic molecular theory of gases
