What is the molarity of each ion in a solution prepared by dissolving 0.500g of Na2SO4 , 1.182g of Na3PO4 , and 0.229g of Li2SO4 in water and diluting to a volume of 100.00mL ?

1. Na=?M

2.Li=?M

3. SO4= ?M

4. PO4=?M

How many moles of each compound are present?
How many moles of each individual ion are in each mole of the compounds?
Add them to get the total moles of each ion present.
Convert moles / 100 ml to moles / L.
There you go!
