Design an experiment to determine the molarity of a saturated solution. Molarity (M) is a unit used to indicate the concentration of a solution. Procedure. NOTE: Consult safety information and obtain teacher approval before beginning the experiment. Design a procedure to prepare a saturated solution and calculate the molarity of the saturated solution.

6)The equation for molarity states that the molarity of a solution is equal to the number of moles of solute divided by the number of liters of solution. In the first equation, the molarity will clearly be equal to 1.0 M, because there are 1.0 moles of NaCl and a solution volume of 1.0 L.

The policeman in charge, never having had a chemistry class, did not seriously consider this to be a motive for murder. Mrs. White, an asthmatic, has a prescription for potassium iodide in the bathroom. Her pharmacist assures us that her potassium iodide solution has a molarity in the range of 0.05 M to 0.15 M.
