Consider the unbalanced chemical equation: H3PO4 (aq) + Ba(OH)2 (aq) → Ba3(PO4)2 (S) + H2O
A volume of 46.0 mL of aqueous Ba(OH)2 solution was required to
react completely with 0.685 g H3PO4 (molar mass = 98.0 g/mol) to
produce Ba3(PO4)2. Calculate the molar concentration of the
Ba(OH)2 solution.
A)0.552 M
B)0.228 M
C)0.403 M
D)0.328 M
E) 0.655 M
