Q4/Answer the items below aa) butyl rubber gloves (0.05 cm thick) are used, what is the diffusive flux of methylene chloride through the glove? diffusion coefficient in butyl rubber: D = 110 x10-8 cm2/s, C1 = 0.44 g/cm3, C2 0.02 g/cm3 bb) Show for the body-centered cubic crystal structure that the unit cell edge length a and the atomic radius R are related through a = 4R/V3. cc) Cite the difference between atomic mass and atomic weight. dd) for figure 1, what is the solubility limit for sugar in water at 25 °C Sugar/Water Phase Diagram 100 O 80 Solubility, Limit (liquid) 60 + 40 (liquid solution i.e., syrup) (solid sugar) 20 100 C = Composition (wt% sugar) 20 40 6065 80 syrup Temperature (°C) Water o

Consider doping of silicon with gallium.Assume that the diffusion coefficient of gallium in Si at 1100℃ is 7*10-13 cm2/s.calculate the concentration of Ga at depth of 2.0 micrometer if the surface concentration of Ga is 1023 atom s/cm3.The diffusion times are 1,2 and 3 hours.

Q2) In an experiment CO₂ absorbed into a water film (thickness = 2.396x10 m) flowing = 2.396 down a vertical wall I m long at 25 °C and 1 atm. The solubility of CO₂ in water is 0.0336 kmol/m' solution. At the middle of the tower height, the penetration of CO₂ was measured and it was found that the concentration at a depth of 30% of the film thickness the concentration was 0.02933 kmol/m' solution. The density and viscosity of the solution ar 998 kg/m³ and 8.94x10 kg/m.s. calculate the mass flux. Answer to 02:
