If I added 27 grams of salt to water and separated the solution with a hot plate, what amount of salt would be left behind?

The correct answer is - 27 grams.

Explanation:

salts contain atoms (ions) like Na+ and Cl, these atoms are electrically charged that leads to a big crystal as they can stick together. Those are too heavy to evaporate.

When you heat the hot plate water evaporates but the salt does not leave vessel so, the concentration of salt in the water increases. In the end, the concentration of salt gets so high and the salt will begin to recrystallize into a solid. When all of the water is gone, you will have salt left behind in the same concentration.

Thus, the correct answer is - 27 grams.
