7.00 mL of 5.00 x 10-3 M Fe(NO3)3 (5.00 times 10 to the minus 3rd power M F e (NO3)3) is added to 7.00 mL of 7.00 x 10-3 M KSCN (7.00 times 10 to the minus 3rd power M KSCN) along with 6.00 mL of water. The concentration of [F e(SCN)2+] was found to be 2.00 x 10-4 M (2.00 times 10 to the minus 4th power M) at equilibrium. How many moles of SCN- (SCN minus) are present in the solution at equilibrium? Express your answer as a decimal number (no exponents).

Question

7.00 mL of 5.00 x 10^-3 M Fe(NO₃)₃ (5.00 times 10 to the minus 3rd power M F e (NO3)3) is added to 7.00 mL of 7.00 x 10^-3 M KSCN (7.00 times 10 to the minus 3rd power M KSCN) along with 6.00 mL of water. The concentration of [F e(SCN)²⁺] was found to be 2.00 x 10^-4 M (2.00 times 10 to the minus 4th power M) at equilibrium. How many moles of SCN^- (SCN minus) are present in the solution at equilibrium? Express your answer as a decimal number (no exponents).
