8.00 mL of 6.00 x 10-3 M Fe(NO3)3 (6.00 times 10 to the minus 3rd power M Fe (NO3)3) is added to 4.00 mL of 8.00 x 103 M KSCN (8.00 times 10 to the minus 3rd power M KSCN) along with 5.00 mL of water. The concentration of [F e(SCN)2+] was found to be 1.00 x 10-3 M (1.00 times 10 to the minus 3rd power M) at equilibrium. How many initial moles of F e3+ are present in the solution? Express your answer as a decimal number (no exponents).
