If the calibration curve for a Beer's Law plot of a protein assay had a slope of 0.433 when absorb acne, A, was plotted as a function of protein concentration, c, in mg/mL. The absorbance of an unknown protein sample was 0.345. What is the concentration of protein in this sample in mg/mL?

Answer 1

Should say absorbancy *, A, was plotted..
My phone autocorrected the word.

Answer 2

A = abc; slope = 0.433 which is a.
Then 0.345 = 0.433*c. solve for c in mg/mL.

Answer 3

Thank you!
I solved for c and received c = 0.797
Would this answer be correct?
