What is the concentration of lithium ions in 0.360 M Li₃PO₄?

Answer 1

Amy,

Look at the chemical formula Li₃PO₄. It tells us that for every 1 mole of Li₃PO₄ there will be THREE mols Li⁺ and 1 mole of PO₄^3- ions. Using this information, we can find the concentration of Li⁺ ions as follows:

0.360 M Li₃PO₄ x 3 = 1.08 M Li⁺
