How can I calculate water moles lost in copper sulfate hydrate using the mass percent of water lost?
thank you for any help on this.
If you know the mass of water lost, you can calculate using stoichiometry the moles of water. Oxygen has a molar mass of 16.00 grams per mole (g/mol) and hydrogen has a molar mass of 1.01 g/mol. In total, water has a molecular weight of 18.02 g/mol, so multiply the mass of your water lost by (1 mol / 18.02 g) because the grams need to cancel.
