Data for the next problems A commercial adsorbent can remove impurities from amyl acetate that meets the rigorous quality control standard set by FDA. This adsorbent is a smooth rigid spherical particle with a density of 2750 kg/m³ and a particle diameter of 8.0 ± 0.01 mm. The porosity of a packed bead containing these particles is 0.36. Amyl acetate is an organic compound with the chemical formula C7H1402 and the molecular weight 130.2 kg/kmol. It has a scent similar to bananas. Amy acetate has a standard density of 876 kg/m³, a melting point of - 71°C, a normal boiling point of 149°C, and has a solubility of 20 g/L in water. The liquid viscosity coordinates for amyl acetate CH3 H3C

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.

1.6 Properties: Diffusivity Estimate the molecular diameter and diffusion coefficient for the proteins ribonuclease (MW 13,700 Da), hemoglobin (MW 68,000), and urease (MW 480,000), assuming the molecules are spherical and the density of each protein molecule is 1.3 g/cm³.

Tin atoms are introduced into a FCC copper crystal, producing an alloy with a lattice pa- rameter of 3.7589 x 10-8 cm and a density of 8.772 g/cm³. Calculate the atomic percentage of tin present in the alloy. Calculate the radius of the largest interstitial void in the FCC y iron lattice. The atomic radi- us of the iron atom is 0.129 nm in the FCC lattice and the largest interstitial voids occur at the (12,0,0), (0,2,0), (0,0,1), etc., type positions.
