Question

An aqueous potassium carbonate solution is made by dissolving 6.286.28 moles of K2CO3K2CO3 in sufficient water so that the final volume of the solution is 4.80 L4.80 L. Calculate the molarity of the K2CO3K2CO3 solution.

Answer 1

So, what is molarity?

Molarity (M) = moles K₂CO₃ per liter of solution.

To find M, we must know the moles of K₂CO₃ and the volume of solution in liters.

moles K₂CO₃ = mass / molar mass

molar mass K₂CO₃ = 138 g / mol

6.28 g K₂CO₃ x 1 mol / 138 g = 0.0455 moles K₂CO₃

liters of solution = 4.80 L

Molarity = 0.0455 moles K₂CO₃ / 4.80 L

Molarity (M) = 0.00948 M
