     Mg(OH)2(s)                   +           H3PO4(аq)       ---------->        H2O(l)          +         Mg3(PO4)2(аq) mаgnesium hydrоxide        phоsphоric acid.                        water                      magnesium phosphate         molar mass Mg(OH)2 = 58.20 g/mol           molar mass H3PO4 = 97.99 g/mol molar mass H2O = 18.02  g/mol                   molar mass Mg3(PO4)2 = 262.86 g/mol Based on the chemical reaction outlined above, if 4.500 grams of magnesium hydroxide (Mg(OH)2) reacts with 32.00ml of a 2.00M solution of phosphoric acid (H3PO4), calculate the theoretical mass of magnesium phosphate (Mg3(PO4)2).
