You record the absorbance of your unknown BSA sample at 0.276. What is the concentration in ug/mL of the unknown assuming you have a standard curve with the line of best fit with y=0.0001x+0.0038 as its equation
The glucose content of samples can be determined using Nelson't test. The equation of the line for the standard curve preapred for varying concentrations of glucose is y = 3.0x + 0.2. Based from this information, determine the glucose concentration (in M) of a strawberry preserve having an absorbance reading of 1.35.
Using the data from the standard curve done previously, you record the absorbance of your extracted milk protein sample at 0.499 at 540nm. What is the mass of the protein in mg assuming you collected 10mL worth of the protein? Your standard curve should have a line of best fit with the equation y=0.0001x+0.0038.
You dissolve a 3.435 gram sample of potato in acid to determine the levels of solanine (the reason why green potatoes are poisonous) and diluted it to a total volume of 500.0 mL. You have also created a standard curve as outlined below. Solve for the ug/gram concentration of solanine in the potato sample. ppm Solanine Std.

Calculate the volume of BSA stock that will be required to make the standard solutions needed to create the BSA standard curve. Be sure to show your work and include the volume of 0.02 M phosphate buffer required to reach a final volume of 1 mL. From a 2,000 μg/mL BSA stock, create 1 mL of each of the following stock solutions in 0.02 M phosphate buffer using individual microcentrifuge tubes: 50 μg/mL, 250 μg/mL, 500 μg/mL, 1,000 μg/mL, 1,250 μg/mL, 1,500 μg/mL. Be sure to properly label all the microcentrifuge tubes before creating the standards.
You wish to determine the %concentration of a stock solution of brilliant blue FCF (MW=792.8grams/mole; extinction coefficient,25=97000M1cm 1). You take 5ul of the stock and dilute up to 1ml. You take 10ul of this dilution an dilute it up to 500ul. Finally you take 1ul from this dilution and dilute it up to 1ml in a 1cm diameter cuvette. You obtain an As91=0.001 SHOW YOUR WORK. Do not forget units. 1. What is your total dilution factor? 2. What is the molar concentration of the dye in the original stock? 3. What is the % concentration of the dye in the original stock?
