These are relative terms. A "concentrated" solution has a higher ratio of solute particles to solvent than a "dilute" one.
The POGIL process is the same, but your teacher likely changed the "grams" or "volumes" in the table. If you blindly copy an answer key from 2019 that uses 58.44 g/mol for NaCl, but your worksheet uses KCl (74.55 g/mol), you will fail.

) and understanding that proper laboratory procedure requires dissolving solute and filling to a final volume, rather than measuring solvent volume alone. For more details, visit Molarity - washburnsciencelies These are relative terms
You have 2 L of 3 M HCl. You remove 1 L and put it into a separate beaker. What is the molarity of the HCl in the new beaker?
Many students guess "1.0 M." However, the POGIL answer key emphasizes that volumes are not always additive due to intermolecular forces, but for ideal solutions, we use ( M_1V_1 = M_2V_2 ). If you blindly copy an answer key from 2019 that uses 58
In this comprehensive article, we will explore the importance of Molarity, the philosophy behind POGIL learning, why relying solely on an answer key can be detrimental to education, and how to effectively use these resources to master the concept of solution concentration.
