How many equivalents of charge are present in 0.5 mol (PO4)3–

1.5 eq. of charge are present.

Explanation:

In therms of charge, 1 equivalent of charge is defined as the moles of a monovalent ion (That is of charge +1 or -1) necessaries to neutralize the charge of the ion that we are studying.

In PO₄³⁻ ion there are 3 equivalents of charge per mole of PO₄³⁻. In 0.5 moles of this ion there are:

0.5 moles PO₄³⁻ * (3Eq. / 1 mol PO₄³⁻) =
