A spent sulfuric acid solution is brought up to strength for a pickling process in a mixer. Spent solution at 3% sulfuric acid (by weight) is mixed with a 50% solution (by weight) to obtain the desired product concentration of 40% acid by weight. All are aqueous solutions. Determine all flow rates on the basis of 100 lbm per hour of product. If the actual flow of the spent stream is 300 lbm per hour. What must the flow rates of the stream be?

A sodium hydroxide solution is to be standardized using KHP (99.5% purity, MW = 204.22). A 1.500-g KHP dissolved in water required 14.84 ml of NaOH solution for the phenolphthalein endpoint. Calculate the molarity of the NaOH solution.

3. Refer to the phase diagram depicted below: When 7 moles of A and 3 moles of B are mixed at 50oC which is then cooled  to 10oC the sample turns into two liquid phases, phase I has mole fraction xB=0.14 (see diagram below).  Find the phase II mole fraction xB, and then calculate the ratio of amount of substance in phase I to that in phase II using Lever rule.  Please enter your answer as a number with two decimals.  for example, if the ratio you calculated is 2:3, you enter as 0.67
