How many Sr2+ ions are present in 0.314 moles of Sr3(PO4)2?

5.67x10²³ ions

Explanation:

By looking at the molecular formula, we can tell that there are three Sr²⁺ ions per Sr₃(PO₄)₂ molecule.

We convert Sr₃(PO₄)₂ moles into Sr₃(PO₄)₂ molecules by using Avogadro's number:

Finally we multiply that number by 3 in order to convert Sr₃(PO₄)₂ molecules to Sr²⁺ ions:

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
