Calculate the molarity of a solution prepared by dissolving 10.0 grams of NaOH and then diluting the solution to 500 mL.

Question

Quizplus · Accepted Answer

To calculate molarity, use the formula: Molarity (M) = moles of solute / liters of solution. First, calculate moles of NaOH: 10.0 g / 40.00 g/mol = 0.25 moles. Then, convert 500 mL to liters: 500 mL = 0.5 L. Finally, calculate molarity: 0.25 moles / 0.5 L = 0.501 M.
