2. Five milliliters (5.00 mL) of 0.002 M Fe* 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 Fe* is remaining? d) What is the total volume in L of the solution?
