Solution

The correct option is D 45.24mL of SO2
Rate of diffusion=Volume of gas diffusedtime taken
rO2=64t
rg=Vt
rO2rg=64V

Option (a)
rO2rH2=MH2MO2
64V=232 or V=256 mL

Option (b)
rO2rN2=MN2MO2
64V=2832 or V=68.42 mL

Option (C)
rO2rCO2=MCO2MO2
64V=4432 or V=54.58 mL

Option (d)
rO2rSO2=MSO2MO2
64V=6432 or V=642=45.25 mL
Hence, the correct answer is option (d).
