Dilutions Worksheet - Reflective Analysis

Where did the 295ml come from?

Why is it important to calculate the molarity of a diluted solution?

Explanation

The 295mL volume came from the original solution being diluted from 250 mL to 295 mL.

Answer

The molarity of the diluted solution will be 0.64 mol/L

When considering the process of dilution in chemical solutions, it is crucial to understand the concept of molarity. Molarity measures the amount of solute present in a specific volume of the solution, usually expressed in moles per liter.

In the given scenario, the initial 250 mL of a 0.75 M K2SO4 solution was diluted with an additional 45 mL of water, resulting in a total volume of 295 mL. By using the dilution formula, we can determine the molarity of the final diluted solution.

Through the calculation process outlined in the answer section, we find that the molarity of the diluted solution is 0.64 mol/L. This demonstrates the reduction in concentration as the original solution was diluted to a larger volume.
