Question

A student dissolved a 40-gram block of a salt in 100 grams of warm water at 45°C. The solution was allowed to cool down to 24°C. The student noticed that some of the salt came out of the solution and settled to the bottom of the beaker. It is later determined that 12 grams of the salt came out of the solution. How many grams of the salt were dissolved in the solution at 24°c 100 grams of warm water , PLEASE HELP ME FAST I ONLY HAVE A COUPLE MIN LEFT TO

Answer 1

Answer:

28

Explanation:

The grams of salt dissolved in the solution was 28, because 40 minus 12 would be 28. I know I'm suppose to subtract 40 by 12 considering the fact, it is 12 grams of salt that came out. The rest of the numbers are irrelevant. (apologies this is a week late.)

Answer 2

The amount of salt that was dissolved in the water is 28 grams of the salt.

What is solubility?

The term solubility refers to the amount of a substance that dissolves in solution. In this case we are told that about  40-grams of salt was added to water but about 12 grams of the salt came out of the solution.

In this case, the amount of salt that was dissolved in the water is 40 g - 12 g = 28 grams of the salt.
