Lactic acid is an important pharmaceutical product that is manufactured by fermentation of glucose. To separate the lactic acid from the biomass, filtration followed by centrifugation is employed. A mix containing 23% by mass lactic acid enters the filtration unit at the rate of 6,456 kg/hour. After filtration, the sludge of lactic acid/biomass contains 12 % by mass lactic acid and the filtrate itself contains 100% lactic acid by mass. The sludge then goes to the centrifuge where the solids generated contain 8% lactic acid by mass and the liquid portion stream has 100% lactic acid by mass. Calculate mass flow rate in kg/hour of the stream leaving the filtration unit containing pure lactic acid. [report number with one decimal e.g. 100.4]

When selling on the street, dealers may not know the purity of the ketamine they have, and thus users do not know exactly how much ketamine they are receiving. It is unlikely that the ketamine is pure, or even that different batches of ketamine have the same purity. Assume the drug the user typically buys is only 25%25% ketamine, and therefore, the user actually dissolved 0.250 g0.250 g ketamine in 1/41/4 cup of water to make the solution instead of 1 g1 g in the previous question. 1 cup=236.5 mL1 cup=236.5 mL What volume of this ketamine solution would the 71.0 kg71.0 kg user have to inject to experience a high at 0.500 mg/kg
The nitrogen content of organic compounds can be determined by the Dumas method.The compound in question is first passed over hot CuO(s): Compound N2(g) + CO2(g) + H2O(g) The gaseous products are then passed through a concentrated aqueous KOH solution to remove the CO2.The remaining gas contains N2 and water vapor.A 0.127-g sample of a compound was treated as above, producing 89.0 mL of N2 saturated with water vapor at 25 °C and 739.3 torr.What is the mass percent of nitrogen in the compound? . The vapor pressure of water at 25 °C is 23.8 torr.
A pipet is used to transfer 5.00 mL of a 1.25 M stock solution in flask "S" to a 25.00-mL volumetric flask "B," which is then diluted with DI H,0 to the calibration mark. The solution is thoroughly mixed. Next, 2.00 mL of the solution in volumetric flask "A" is transferred by pipet to a 50.00-mL volumetric flask "B" and then diluted with DI H,0 to the calibration mark. Calculate the molarity of the solution in vol- umetric flask “B."
