Question

A student performs a dehydration experiment and starts with 6.79 grams of hydrate. After heating the hydrate and allowing it to cool, the student weighs the anhydrous salt. The mass of the resulting anhydrous salt is 3.17 grams. What is the mass of the water that was lost?

Answer 1

The mass of the water that was lost is 3.62 grams.

Step-by-step explanation:

To find the mass of the water that was lost, we subtract the mass of the anhydrous salt from the initial mass of the hydrate. The mass of water lost is 6.79 g - 3.17 g = 3.62 g.
