Once the moles are calculated, the mass of KCl required to prepare the solution can be calculated. If a known amount of solid is dissolved and diluted to a final volume, the molarity of the solution can be calculated. If you dissolve 0.7500 g of NaCl in water and dilute it to a final volume of 100.00mL, you would calculate the molarity as follows:
