What is the molarity of a 0.30 L solution containing 0.50 moles of NaCl?
One way of expressing the concentration of chemical substances in a solution is known as molarity, in which the concentration of the substance is expressed using the quantity of the moles of solute in a liter of solution. In order to calculate molarity, the number of moles of the solute present must be divided by the solution's volume in liters. The concentration, then, can be expressed in the symbol M meaning molar.
