Answer #1

1) Solids that contain watermolecules as part of their crystalline structure are known as hydrates.Water is chemically bound in a compound, usually ionic, so that thewater molecules become part of the crystal structure and are present indefinite proportions relative to the other ions.water of crystallization or water of hydration or crystallization water is water that occurs inside crystals

2)That shows that the compound is a hydrate. That means that for every one mole of anhydrous (without water) Salt, there are n moles of H2O attached. Any hydrated compound will have that dot, and those waters attached will change the molar mass.

3) one, zeros preceeding the first non digit number are not significant

6) one ,
