Postlab problems Use your calibration equation and the lab introduction to answer the foñlowing questiorvs. 1. A solution is found to have a transmittance of 0.091. For this sohution, calcauiate the absorbance of the solution, and the (FeSCN2'1 in the solution. 2. A solution is found to have a percent transmittance of 31.4%. Calculate the absorbance and the [FeSCN2'1 for this solution. 225.00mL of 0.200M Fe(NOj)s a. Calculate the expected concentration of FeSCN, assuming that the reaction 3. A solution is prepared by mixing 25.00mL of 0.00200M KSCN with that forms the complex ion proceeds completely to the right. Based upon your calibration, calculate the absorbance expected for this solution. b. c. Calculate the expected percent transmittance. 4454.5 - loo 5A-7
