A solution of sodium carbonate, Na₂CO₃, is prepared by dissolving 25 grams of sodium carbonate in water to produce 450 mL of solution. What is the molar concentration? [MM = 105.9888 grams/mole]

Question

Quizplus · Accepted Answer

To find the molar concentration, divide the number of moles of solute by the volume of the solution in liters. Moles of Na2CO3 = 25 g / 105.9888 g/mol = 0.2358 mol. Volume in liters = 450 mL / 1000 = 0.45 L. Molar concentration = 0.2358 mol / 0.45 L = 0.524 M.
