Magnesium phosphate is used as a dental polishing agent. how many moles of ions (cations and anions together) are in 1 mole of magnesium phosphate, mg3 (po4) 2?

The answer to this question would be:5 mol

To answer this question, you need to know the chemical equation of mg3 (po4) 2 when forming an ion. The equation should be: mg3 (po4) 2 = 3Mg (2+) + 2PO4 (3-)

That means for 1 mol of mg3 (po4) 2 there will be 3 magnesium (cation) ion and 2 phosphates (anion) ion, the result would be 5 mol of ion.
