Question

An aqueous potassium carbonate solution is made by dissolving 6.35 moles of K 2 CO 3 in sufficient water so that the final volume of the solution is 4.30 L . Calculate the molarity of the K 2 CO 3 solution.

Answer 1

Answer:

The molarity of the solution is 1,48M

Explanation:

In chemistry, molarity, M, is an unit of concentration that represent the ratio between moles of solute and volume of solvent in liters.

In the problem, the solute is potassium carbonate, K₂CO₃, and the solvent is water.

There are 6.35moles of potassium carbonate and 4.30L of water. That means molarity is:

6,35mol / 4,30L = 1,48M
