    Hi CalmSwan8973,

    Thanks for your question!

    To find the amount of calcium ions in 0.519 mol of calcium phosphate we need to look at the calcium phosphate molecule first. Here's the chemical formula of calcium phosphate : Ca3(PO4)2.

    As you can see, there are three calcium ions in one calcium phosphate molecule.

    In your problem, you know the amount of calcium phosphate molecules. You can find the amount of calcium ions in mol and then convert this value in the number of ions to find the answer.

    Also, don't forget that in one mol there's 6,022x10^23 particles.

    I hope that helps and feel free to write us again!
