Astudent prepareda calibration curve by plotting absorbance of the standards against the [FeSCN2+] molar concentration (M). The best fit line of the linear equation for the student's experiment was createdas y= 0.1827x-0.0513 (Spec 20). Determine the equilibrium concentration of iron in unknown solution if the absorbance for the unknown solution was measured to be 0.308.
