Hello! Can someone please explain making solutions involving chemicals in hydrate form? I am using a calculator which has worked well for all chemicals except hydrates.
When using this calculator, I obtain different values for making a 1.0 molar solution of CuSO4 pentahydrate than the Flinn Scientific solutions cheat sheet has.
For example, to make a liter of solution, the Flinn Scientific sheet says this:
|Copper(II) sulfate||1.0 M||249.7 g|
The calculator says this:
Use 145.6358 grams to prepare: 1000 mL of 1.0 M CuSO4.5H2O
Can someone please clarify?
