- How would you prepare 75 mL of an H2SO4 solution at 20% in weight (density=1.1394 g/mL, richness=227.9 g/L) starting from the commercial H2SO4 solution (98%, density=1.8361 g/mL, richness=1799 g/L)? Please choose among the most appropriate procedure which better describes the preparation of the previous diluted H2SO4 solution: Select one or more: a. Take the required volume of commercial H2SO4 solution with an adequate pipette, pour it into a graduated flask and add water up to the final volume (75 mL in this case). Homogenize the flask by stirring it gently. b. Take a beaker and put about 40 mL of distilled water. Then take the required volume of commercial H2SO4 solution with an adequate pipette and pour them over the beaker. Let the solution be warm and pour the mixture into a graduated flask and add water up to the final volume (75 mL in this case). Homogenize the flask by stirring it gently. c. Take a beaker and put about 40 mL of distilled water. Then take the required volume…A chart is prepared by plotting In Ksp versus 1/T, using data obtained by performing a lab experiment. Refer to the attached photo for reference on how to solve these equations.

- A solution containing 100 lbm KNO 3/100 lbm H 2O at 80°C is fed to a cooling crystallizer operated at 25°C. Slurry from the crystallizer (KNO3 crystals suspended in saturated solution) is fed to a filter, where the crystals are separated from the solution. Use the solubility data in Figure 6.5-1 to determine the production rate of crystals (lbm/lbm feed) and the solid-to-liquid mass ratio (lbm crystals/lbm liquid) in the slurry leaving the crystallizer.Calculate the Constant Weight (in grams) of the Empty Crucibles.
