Problem: 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?

FREE Expert Solution

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:


molarity (M)=moles soluteL solution
