2. Five milliliters (5.00 mL) of 0.002 M Fe3+ is mixed with 3.00 mL of 0.001 M of SCN and then 2.00 mL of aqueous solution is added. Assuming that the volumes are additive, calculate the final concentration (in M) of Fe3+ in the mixture. Fe3+ and SCN react to form FeSCN2+ in a 1:1 mole ratio. a) Determine initial Fe3+ moles b) Determine initial SCN moles c) After the reaction, how many moles of Fe3+ is remaining? d) What is the total volume in L of the solution? e) Calculate the final concentration of Fe3+
