The root mean square speed of one mole of a monoatomic gas having molar mass

M

u_{rms}

. The relation between the average kinetic energy (

E

) of the gas and

u_{rms}

is : (1)

u_{rms} = \sqrt{\frac{3E}{2M}}

(2)

u_{rms} = \sqrt{\frac{2E}{3M}}

(3)

u_{rms} = \sqrt{\frac{2E}{M}}

(4)

u_{rms} = \sqrt{\frac{E}{3M}}
