A student stated that the solubility of KCL, at 20 degrees Celsius was 36 grams of KCL per 100 grams of solution. What is wrong with this statement?

I think maybe you better look up the solubility which is normally in grams or mols per liter but 36 grams in 100 grams is much higher than believable by any stretch of the imagination. A liter of fresh water is about a 1000 grams.
The statement made by the student regarding the solubility of KCL (potassium chloride) at 20 degrees Celsius is incorrect. The solubility of a substance is typically expressed in terms of the maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature.
To determine what is wrong with the student's statement, we need to compare it with the actual solubility data for KCL at 20 degrees Celsius.
To find the solubility of KCL at 20 degrees Celsius, one way is to consult a reliable source such as a chemistry reference book, a scientific journal, or an online database. These sources provide experimental data that have been measured and verified by scientists.
Upon checking such a source, you might find that the correct solubility of KCL at 20 degrees Celsius is actually different from the student's statement. Let's say, for example, that the correct solubility of KCL at 20 degrees Celsius is 35 grams of KCL per 100 grams of water.
In this case, the student's statement of 36 grams of KCL per 100 grams of solution is incorrect as it exceeds the actual solubility limit. This means that the student's claim goes beyond what is physically possible.
