We want to ultrafilter 840 L of a solution containing 0.061 wt% of a protein used as a vaccine for herpes. This protein has a diffusion coefficient of 1.1 x 106 cm²/s and a molecular weight of 16,900. We would like to get the concentration up to about 2% by weight. The ultrafilter, which we hope to use, has eight hollow fiber cartridges, each of which has a surface area of 1.20 m?. It is cooled to 4°C during the operation. The membrane in these cartridges gives an initial flux of 5.7 x 105 cm/s under a pressure drop of 31 atm. Assuming negligible concentration polarization, estimate the time to complete this filtration.

A empty evaporating dish weighs 30.56g. You place 20.0mL of an NaCl solution in the dish plus the solution weighs 53.31g. You evaporatorate the solution to dryness ant find that the evaporatoring dish plus the residue weighs 32.25g. What is the w/v%? What is the w/w%? What is the molarity?
Downvoted for wrong solution. A river is carrying water containing 2000 mg/l Magnesium Chloride into a small lake. The lake has a naturally occurring Magnesium Chloride of 50 mg/l. If the river flow is 2500 Lmin and the lake flow rate is 1.5 m³.sec¹, what is the concentration of MgCl2 in the lake after the discharge point? Assume that the flows in the river and lake are completely mixed, that the salt is a conservative substance, and the system is at steady state.

Using the Poiseuille formula, the viscosity of carbon dioxide was measured by comparing its flow rate through a long, narrow tube with that of argon. For the same pressures, the same volume of carbon dioxide passed through the tube in 55 s as argon in 83 s. The viscosity of argon at 25 °C is 208 μP. What is the viscosity of carbon dioxide? Give your answer in μP
