The amount of protein in a sample is measured by the samples absorbance of light at a given wavelength. Using standards, a best fit line of absorbance vs. mg protein gave the following parameters:                                     m = 0.01630    sm = 0.00022                                                             b = 0.1040                                sb = 0.0026 An unknown sample has an absorbance of 0.246 ± 0.0059. What is the amount of protein in the sample?
