A question in analytical chemistry.

I performed an EDTA titration. Based on the Calcium carbonate, the EDTA concentration was 5.294*10^-3 mol/L

find the concentration of Ca2+ and Mg2+ in a sample.

The sample titrated was 5 mL, the whole sample 100 mL (microwaved digested) and the mean EDTA volume used was 4.88mL.

Can you please show me how to calculate.
