CHXI06:STATES OF MATTER

314138 Sulphur dioxide and oxygen were allowed to diffuse through a porous partition. \(\mathrm{20 \mathrm{dm}^{3}}\) of \(\mathrm{\mathrm{SO}_{2}}\) diffuses through the porous partition in 60 seconds. The volume of \(\mathrm{\mathrm{O}_{2}}\) in \({\rm{d}}{{\rm{m}}^{\rm{3}}}\) which diffuses under the similar condition in 30 seconds will be (atomic mass of sulphur = 32 u):
