I need the answer as soon as possible

Example-1.4) Measurment of Molecular Diffusivity Molecular diffusivity of iodine (A) in air (B) will be measured at 760 mmHg and 25 C. For this, solid iodine cast in spherical shape with 4 mm diameter is suspended in a duct through which air flows. After 22 hours and 54 minutes, iodine sphere completely disappears. What is the value of molecular diffusivity? Vapor pressure and density of solid iodine at 25 C are 1.07 mmHg and 4 930 kg/m. M.=254. Givens: Asked : A: Iodine, B: Air 2 DAR =? AB B P= 760 mmHg, t = 25 C do = = 4 mm 0= 22 h and 54 min Gas film p=1.07 mmHg Pa = 4 930 kg/m3
