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 = 15.5 g NaOH (1 mol NaOH / 40 g NaOH)  / .250 L
solution

Molarity = 1.55 M
