Which of the following methods results in the most sensitive method? A) All 3 methods have equal sensitivity. B) The most sensitive method cannot be determined from the information given. C) B D) A E) C

A calibration curve was created to determine the quantity of protein in a solution. The calibration curve has the form of a straight line with the equation ?=0.0182?+0.007 where ? is the corrected absorbance of the solution and ? is quantity of protein in the solution in units of micrograms (μg). Determine the quantity of protein in a solution that has an absorbance of 0.305. A blank solution has an absorbance of 0.060. The answer (Quantity of protein) should be in units of (μg)

A solution of a dye was analyzed by spectrophotometry, and the following calibration data were collected using a 1 cm cuvette. *graph in attachemnt*   Using the calibration data above for the dye solution, what is the dye concentration in a solution with an absorbance (A) = 0.52 if it was measured in a 1 cm cuvette?   Group of answer choices 3.0 x 10-6 M 6.0 x 104 M 2.0 x 10-6 M Not enough information is provided.

can you explain how I can get 1.596 mg/L of concentration of Fe3+ in dilutes sample and can you also make the calibration curve.
