Compute the molarity of a solution made by adding 27.3mL of concentrated potassium hydroxide (34.5 % by mass, density 1.46 g/mL) to some water in a volumetric flask then adding water to the mark to make exactly 250mL of solution. It is significant to add concentrated acid or base to water, rather than the other way to minimize splashing and maximize safety.
