Question:

What is the molarity of a solution made by dissolving 25.0 g of {eq}H_3PO_4 {/eq} in 150.0 mL of solution?

Chemical Solution Concentrations:

Each expression of the concentration of a solution has a specific purpose in chemistry. As an example, we often use the molal (moles of solute per kg of solvent) concentration (molality) of a solution when calculating the freezing point of the solution upon the addition of a non-volatile solute. On the other hand, molar (moles of solute per liter of solution) concentration (molarity) can be used when no change in temperature or pressure is occurring.
