Problem- 4.75 mL of H2O and 2.50 mL of an aqueous 0.010 M SCN- solution were added to 11.25 mL of an aqueous 0.015 M Fe3+ solution. The total volume of the solution is 18.50 mL.
1) What is the diluted Fe3+ concentration?
A standard reference FeSCN2+ solution (0.040 M) has an absorbance = 1.025.
2) What is the concentration of an unkown FeSCN2+ solution that has an absorbance = 0.431.
Explain each and every step in detail. I need proficient help in the above problems.
