A reaction mixture of 4.00 mL of 0.00200 M SCN and 5.00 mL of 0.00200 M Fe^3+ is diluted to 10.00 mL with 0.1 M HNO3 to form the blood-red FeNCS^2+ complex. The equilibrium molar concentration of the FeNCS^2+ determined from a calibration curve, is 1.5 x 10^-4 mol/L. Calculate, in sequence each of the following quantities in the aqueous solution to determine the equilibrium constant for the reaction.

Fe^3+(aq) + SCN-(aq)<--------FeNCS2+(aq)-------->

a. moles of FeNCS^2+ that form in reaching equilibrium

b. moles of Fe3+ that react to form the FeNCS^2+ at equilibrium

c. moles of SCN- that react to form the FeNCS2+ at equilibrium

d. moles of Fe^3+ initially placed in the reaction system

e. moles of SCN- initially placed in the reaction system
