Acalibration 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 =0.0182x+0.007 a=0.0182x+0.007 where is the corrected absorbance of the solution and xx 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 0.2320.232 . a blank solution has an absorbance of 0.0950.095 .
