What is the concentration in molarity of a solution in which 1.10 grams of potassium iodide, KI, is dissolved in water to produce 125 mL of solution?

Question

Quizplus · Accepted Answer

To find the molarity, first calculate the moles of KI: Molar mass of KI = 39.10 (K) + 126.90 (I) = 166.00 g/mol. Moles of KI = 1.10 g / 166.00 g/mol = 0.00663 mol. Molarity = moles/volume (L) = 0.00663 mol / 0.125 L = 0.0530 M.
