A student mixes 5.00 mL 2.00x10-3 M FeCl3 with 3.00 mL 2.00x10-3 M KSCN. She finds that in the equilibrium mixture the concentration of FeSCN2+ is 1.28x10-4 M. Find Keq for the reaction a. Find the number of moles Fe3+ initially present. b. Find the number of moles SCN- initially present. c. What is the volume of the equilibrium mixture? d. How many moles of FeSCN2+ are in the equilibrium mixture?
