Answer :


Mass of hydrogen gas=0.5g

Volume of cubic chamber

No. of moles of hydrogen =

No. of molecules of hydrogen is given by

Volume of a single molecule is approximately

Therefore, volume occupied by n molecules of hydrogen =

We know that

From ideal gas equation

When T is constant, then


We have

Using eqn.(i) we have

Which is approximately equal to the molecular volume of gas. Hence the intermolecular forces between the molecules cannot be neglected and the ideal gas laws do not follow here.
