Question:
If 40.0 mL of 11.25 M KNO{eq}_3 {/eq} is used to make a 7.55 L aqueous solution, what is the molarity of the solution?
Dilution of Solutions:
The dilution of a solution is done on solutions known as stock solutions. The stock solution is an abundant solution with a great volume and a known concentration. A part of this solution is taken and then added with a certain amount of solvent to decrease the concentration. The result is a diluted solution.
