Answer:

#"Phosphoric acid"# acts as a DIACID in aqueous solution........

Explanation:

And thus we write the stoichiometric equation:

#H_3PO_4(aq) + Mg(OH)_2(s) rarr Mg^(2+)HPO_4^(-)(aq) + 2H_2O(l)#.

Given the 1:1 stoichiometry (and 1:2 stoichiometry with respect to water, #0.48*mol# of water will be generated, i.e. approx. #9*g#.
