4 mL of 5 x 10-3 M Fe(NO3)3 is added to 6 mL of 8x10-3 MKSCN along with 4 mL of water. The concentration of FeSCN2+ was found to be 3 x 10-4 at equililibrium. How many initial moles of Fe3+ are present in the solution? How many initial moles of SCN-are present in the solution? How many initial moles of FeSCN2+ are present

Introduction-
The reaction is said to be in equilibrium if both the forward and backward reaction is in same pace. In this kind of reaction, the equilibrium constant expression in the terms of concentration (Kc) is the ratio of product of product concentration to the product of reactant concentration.
For a chemical reaction in equilibrium, "aA + bB⇔cC + dD " ,
Kc is the molar equilibrium constant and it is given as-
[A],[B],[C] and [D] are the concentrations of reactants and products respectively and a,b,c and d are the no. of molecules respectively.
