A standard of solution was put through appropriate dilutions to give the concentrations of glucose (mM) shown in the accompanying table. The absorbances in the table (1.00-cm cells) were recorded at 490 m table. Use the method of least squares to find an equation relating absorbance and the concentration of glucose.
