Question- A 48.60 mL aliquot from a 0.470 L solution that contains 0.400 g of MnSO4 (Fw = 151.00 g/mol) required 40.5 mL of an EDTA solution to reach the end point in a titration. What mass (in milligrams) of CaCO3 (FW = 100.09 g/mol) will react with 1.47 mL of the EDTA solution?
Anyone can tell me how to solve it step by step so that I will be able to understand what is going on?
