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. Josh should calculate the moles of the sodium nitrate by dividing the mass with the molar mass of sodium nitrate. This is because it is the solute in this problem.
