Name Lab Day circled: Mon. Tues. Wed. Thurs. Prelaboratory Exercise for Spectrophotometric Determination of Equilibrium Constant Experiment 1. A Beer's law plot of [FeSCNI versus absorption yielded a straight line with the formula, absorbance 4631 x [FeSCNI. Complete the following calculation if a mixture made from 5.00mL of 0.00200 M Fe(NO,)s mixed with 3.00mL of 0.00200 M KSCN and diluted to 10.00mL has an absorbance of 0.700. Show the setup for each of your calculations. a) From the straight line equation above, determine the molarity of IFesCNI 3 in the solution with an absorbance value of 0.700- set up: b) The moles of FeSCN (M x V in liters) in the 10.00mL, volume of the solution from la) set up: c) Mole Fe" complexed in the sample in 1b- set up: d) Total moles of Fe" in the 5.00ml. sample of 0.00200 M Fe(NOs)s used to make the mixture tested- set up: e) Mole Fe" uncomplexed (total moles Fe" - moles Fe complexed)- set up
