10. The 1/v axis of a reciprocal plot is labeled 10° The 1/[S] axis is labeled [S]*': (M)'× 10.) The plot intersects the two axes at “2" and "-4," respectively. What are Vmax and Km ? v: (nmoles x literx min)×

Sugar Cane Solution Evaporation. Evaporator is used to thicken sugar cane solution. The feed rate is 10,000 kg / day, wherein the solution contains 25% (w / w) solid sugar. The result of thickening is that of a 65% (w / w) solution of solid sugar. Calculate the weight of the solution produced and the amount of air removed. (a) The weight of the solution produced = Answerkg (b) The amount of air removed = Answerkg

An HPLC method was developed for the separation and determination of ibuprofen in blood samples. A 3.00 mL blood sample dissolved in 70.00 mL solvent was prepared and 10.0 mL was injected into the HPLC. Standard ibuprofen solutions were also run.Calculate the ibuprofen present in the 3.00 mL blood sample The following data were obtained.
