You know the mass of the crucible empty. You know the mass of the crucible with the hydrate before heating it. You know the final mass of the crucible and the "dry" salt left behind.

What is the mass of just the hydrate before heating?

What is the mass of just the salt left behind?

That should get you most of the way there.

So I found the masses for all of the above and it's asking me to write generic word equation and a chemical equation for the reaction that occurs when an anhydrous salt is placed in water (hydrated)? How do i find the generic word equation? D:
