Calculate the molarity of unreacted salicylic acid in the student's aspirin sample using the equation for the linear regression line. To do this, substitute the absorbance of the synthesized aspirin sample in the equation for "y" and solve for "x". Report your answer in scientific notation with 3 significant figures. Do not include the units in your answer. mol/L Absorbance
