Quantum states of electrons are usually written in terms of four numbers: the principle quantum number (n), the angular momentum azimuthal number (L), the magnetic quantum number (ml), and the spin projection number (ms). The quantum number set (4,1,0,+1/2) and (4,1,1,+1/2) share the same principle quantum numbers and therefore both sit in the n=4 electron shell.

Calculate the ratio of effusion rates for helium and argon.
lys-0071 [83]

Answer : The ratio of effusion rates for helium and argon is 3.2 : 1

Solution : Given,

Molar mass of Helium = 4 g/mole

Molar mass of Argon = 40 g/mole

Rate of effusion : It is defined as the rate of effusion of a gas is inversely proportional to the square root of the molar mass of the gas.

Formula used :

\text{Rate of effusion}=\frac{1}{\sqrt{M}}

where, M is the molar mass.

\frac{Rate_{He}}{Rate_{Ar}}=\sqrt{\frac{M_{Ar}}{M_{He}}}

Now put all the given values in this expression, we get

\frac{Rate_{He}}{Rate_{Ar}}=\sqrt{\frac{40}{4}}=\frac{3.2}{1}

Therefore, the ratio of effusion rates for helium and argon is 3.2 : 1
