Understand the concept of molarity, which is defined as the number of moles of solute divided by the volume of solution in liters. The formula for molarity (M) is: , where is the number of moles of solute and is the volume of the solution in liters.
Identify the given values in the problem: 1.22 moles of KI and 1.15 liters of solution.
Substitute the given values into the molarity formula: .
Perform the division to calculate the molarity. This involves dividing the number of moles of KI by the volume of the solution in liters.
Compare the calculated molarity with the provided options to determine which one matches the result.
