From the following experimental data identify the unknown strong electrolyte hydrate with the general formula of:
Mx(A)Y . z H20

A-n is an oxyanion. When 30.0 mg of anhydrous NanA is fully reduced 15.26 mL of a 0.2313 M Solution of the reductant is needed. The reaction is known to occur in a 1:1 molar ratio.

The cation is a silvery white metal that normally has a cubic unit cell structure, a density of 5.24 g/cm3 and an oxidation state that is trivalent.
When 33.45 mg of the unknown is dissolved in 10 mL of water at 25 C the resulting solution is found to have an osmotic pressure of 588 torr.
