Which aqueous solution will have the highest total number of moles of ions in the solution? The answer is 100mL 3M calcium nitrate. Why is it not 100mL 4M glucose (C6H12O6), 100mL 1M aluminum fluoride, or 100 mL 2M calcium sulfide? How do you calculate the total number of moles of ions in the solution?
