1. There are a number of ways to express concentration of a solution. This includes molarity. Molarity is expressed as the number of moles of solute per volume of the solution. The concentration of the solution is calculated as follows:
Molarity = 612 g (1 mol / 110.96 g) / 3.04 L
Molarity = 1.81 M
1.81 M is the polarity of a solution that contains 612 grams of CaCl2 in 3.04 liters of solution.
