300.0 g of a solution of NaCl in water has a freezing point depression of -22.9 oC.  If a saturated solution contains 36.0 g NaCl/ 100 mL, is the described solution saturated?  Kb water 1.86 C/ m. PLEASE HELP!

It is desired to reduce the 2% CO, in 23 lb/sec of a natural gas stream using absorption in aqueous diethylamine flowing at 40 lb/sec. Either 1 ½ in. Raschig rings or 1 ½ in. Pall rings are being considered for packing. A pressure drop of 0.25 in H2O/ft is desired to minimize foaming. Under operating conditions, the densities of the gas and the liquid are 2.8 and 63 Ib/ft³, respectively; the liquid viscosity is 2 centistokes. "Determine the flooding velocity and the tower's cross-sectional area using the succeeding procedures

In a counter-current absorption tower, a process gas containing 0.04 (mole fraction) ammonia is scrubbed with pure water. The exit gas contains 0.002 (mole fraction) ammonia.The diameter of the tower is 1m, and the packing has a large area per volume of 200 m2m–3. The overall mass transfer coefficient based on the liquid side driving force, KL, is 1.5×10−5ms–1. The total gas and liquid concentrations are 0.6kmolm–3and 20 kmolm–3respectively and the gas flowrateis 0.03kmols–1. The actual liquid to gas ratio is 1.5 times that of the minimum liquid to gas ratio. The equilibrium for ammonia between the air and water is given by y* = 1.04x. If the operator increases the gas flow by 20% while keeping the liquid flow and the entering gas and liquid compositions constant,what are the new mole fractions of ammonia in the exit gas and the exit liquid? Assume that the overall mass transfer coefficient does not change with the gas flow.
