We’re being asked to calculate the molarity (M) of an aqueous solution that has a mass of 490 grams containing 8.5×10–3 grams of calcium ions.
Recall that molarity is the ratio of the moles of solute and the volume of solution (in liters). In other words:
An aqueous solution has a mass of 490 grams containing 8.5×10–3 grams of calcium ions. What is the concentration of calcium ions in this solution?
