B. The diffusivity of carbon tetrachloride, CCl4 through oxygen O₂, was determined in a steady state Amold evaporating cell. The cell, having a cross sectional area of 0.82 cm², was operated at 273 K and 755 mmHg pressure. The average length of the diffusion path was 17.1 cm. If 0.0208 ceof CCl4 was evaporated in 10 hours of steady state operation, what should be the value of the diffusivity of CCl4 through oxygen?
