The concentration of purified OXA-M290 is tested with a BCA assay. Serial dilutions of a bovine serum albumin (BSA) stock solution are prepared, then pipetted into a 96-well plate; each dilution of the BSA standard is tested in triplicate. Then, bicinchoninic acid and Cu2+ ions are added to all of the wells of the plate. After incubating the plate for 1 hour, a microplate reader is used to measure the absorbance of all of the wells in the plate at 560 nm. This generates the following data: BSA conc. (μg/mL), Replicate 1 Absorbance, Replicate 2 Absorbance, Replicate 3 Absorbance 40, 1.360, 1.403, 1.481 20, 0.750, 0.745, 0.810 10, 0.380, 0.344, 0.398 5, 0.198, 0.160, 0.183 2.5, 0.090, 0.100, 0.085 1.25, 0.038, 0.043, 0.051 0.625, 0.024, 0.028, 0.019 Prepare a calibration curve using these data.

A sample of steel (0.506 g) was digested in acid and the solution made up to 100 cm3 with deionised water. Aliquots (25.0 cm3) of this solution were transferred into two volumetric flasks (100 cm3) labelled A and B. Flask A was made up to volume with deionised water. To flask B was added 10.0 cm3 of a 260 ppm standard solution of Mn2+ which was then also made up to volume with deionised water. The following absorbance results were obtained: Solution A = 0.356, Solution B = 0.578. Use these results to calculate the percentage (% w/w) of manganese in the steel sample.
Note: Express % strength with 4 decimal places. For ratio strength, state the volume only% Astelin nasal spray contains 0.1% azelastine hydrochloride and 125 mcg/mL of benzalkonium chloride as a preservative. A container is capable of delivering 200 metered sprays of 0.137 mL each. The percent concentration of benzalkonium chloride in the preparation is _______%, which is equivalent to a ratio strength of 1 in _____ w/v.
The partition coefficient of ammonia between water and chloroform is wanted to be determined. The necessary quantities of ingredients are taken into the separation funnel, and the extraction process is applied. At the end of the extraction process, 5 mL portions of each of the water and chloroform phases are titrated with 0.1 M HCI in the presence of methyl orange indicator. If the volumes spent at the turning points are 7.2 and 5.1 mL, respectively, calculate the KSU, KLOROFORM (Dispersion coefficient) value.
