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 A = 0.0182 x + 0.007 A=0.0182x+0.007 where A A is the corrected absorbance of the solution and x x 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 0.300 0.300 . A blank solution has an absorbance of 0.072 0.072 .
