Post 2 Chemical Composition

So we are now learning about hydrate compounds and anhydrates. The nomenclature of hydrates stays relatively the same, but don't forget to name the number of water molecules (type III prefixes) before the hydrate/hydride. To calculate this number convert both the mass of the crucible and the mass of the hydrate to moles using the amount in grams divided by the total mass of the molecules/compound. You then divide the large number (moles of H20) by the smaller (moles of anhydrous salt) to get x (value of hydrate).
Here's a reminder over the nomenclature. purdue
And here's a practice of my worksheet.
