QUESTION 10 (4b-401-1.53-1) An intern working in a research lab knocks over a beaker containing an important solution. The beaker originally contained 1.50 L of a 1.53 M solution, but after it spilled it only contained 1 L of solution. The intern decides to hide his mistake by refilling the beaker to contain 1.50 L again by adding pure water (not realizing that this will dilute the solution).
