The correct formula for Molybdenum(IV) Phosphate is Mo₃(PO₄)₄. Here's how to break it down:

* Molybdenum(IV) indicates that molybdenum has a +4 charge (Mo⁴⁺).

* Phosphate is the polyatomic ion PO₄³⁻.

To balance the charges, we need three molybdenum ions (3 x +4 = +12) and four phosphate ions (4 x -3 = -12). This results in the formula Mo₃(PO₄)₄.
