In deriving the kinetic gas equation,use is made of the root mean square velocity of the molecules because it is

The increasing order of the rate of diffusion for the gases $H_2$,$O_2$,$NH_3$,and $CO_2$ is:

In which of the following pairs do the gaseous species diffuse with the same rate of diffusion under similar conditions of temperature and pressure?

The density of a gas at $100 \, kPa$ pressure is $0.1 \, g \, dm^{-3}$. The root mean square speed of the gas in $ms^{-1}$ is:

$RMS$ velocity of one mole of an ideal gas was measured at different temperatures. $A$ graph of $(u_{rms})^2$ (on y-axis) and $T(K)$ (on x-axis) gave a straight line passing through the origin and its slope is $249 \ m^2 \ s^{-2} \ K^{-1}$. What is the molar mass (in $kg \ mol^{-1}$) of the ideal gas? $(R=8.3 \ J \ mol^{-1} \ K^{-1})$

Which of the following equations does not represent the root mean square velocity $(u_{rms})$?
