Answer is: The molar solubility of ba3 (po4) 2 is 6.00 x 10-39.

Balanced chemical reaction: Ba₃ (PO₄) ₂ (s) → 3Ba²⁺ (aq) + 2PO₄³⁻ (aq).

s (Ba₃ (PO₄) ₂) = 8.89·10⁻⁹ M.

[Ba²⁺] = 3s (Ba₃ (PO₄) ₂) = 3s.

[PO₄³⁻] = 2s.

Ksp = [Ba²⁺]³ · [PO₄³⁻]².

Ksp = (3s) ³ · (2s) ².

Ksp = 108s⁵.

Ksp = 108· (8.89·10⁻⁹ M) ⁵.

Ksp = 108 · 5.55·10⁻⁴¹ = 6·10⁻³⁹.
