Chemists use molarity to express quantitatively the concentration of a solution.
By learning the calculations and proper lab techniques involved in solution preparation, students relate the theoretical skills learned in the classroom to the practical techniques required in the laboratory. Both are essential for quantitative analytical work. Students will need volumetric flasks for this activity. Note that students are frequently confused about which volume molarity is based on. Emphasize that the volume used in the molarity calculation is total volume of the solution, not the volume of the solute added.
