Analysis of Aluminum in a Mixture by Solvent Extraction and EDTA Titration. *the amount of EDTA, which is equivalent to the number of moles of zinc and the number of moles of aluminium.* A sample required 9.73 mL of zinc nitrate solution to titrate the EDTA released from aluminum through the addition of fluoride. If the molarity of the zinc solution was 0.025M and EDTA was 0.05M, what was the total weight of the aluminum present in the initial sample?

An unknown solution was analyzed for Ni by an EDTA titration. A 50.00 mL sample of the unknown was treated with 25.00 mL of 0.2404 M EDTA. The excess EDTA was then back titrated with 8.52 mL of 0.0694 M Zn2+ to reach the equivalence point. What was the concentration of Ni (in unit of M) in the 50.00 mL sample? Please keep your answer to three decimal places.
