A mixture of 2 moles of helium gas `(atomic mass=4amu)` and 1 mole of argon gas `(atomic mass=40amu)` is kept at 300K in a container. The ratio of the rms speeds `((v_(rms)(helium))/((v_(rms)(argon))` is

A mixture of 2moles of helium gas (atomic mass=4 amu) and 1 mole of argon gas (atomic mass=40 amu) is kept at 300 K in a container. The ratio of the rms speeds is

A mixture of 2 moles of helium gas ( (atomic mass)=4a.m.u ) and 1 mole of argon gas ( (atomic mass)=40a.m.u ) is kept at 300K in a container. The ratio of the rms speeds ((v_(rms)(helium))/((v_(rms)(argon)) is

What is the mass of :) 5 moles of helium atoms (Atomic mass of helium= 4) ?

Calculate the r.m.s. velocity of argon (atomic mass = 40) at N.T.P.

The rms speed of helium in ms^(-1) (atomic mass = 4.0g mol^(-1) ) at 400K is
