Answer :

Given:


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



..(i)


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.
