on heating the hydrate CaSO4*2H2O, how many moles of water should be driven off per mole of hydrate?
1 mole?
Wouldn't it be 2 moles water per 1 mole CaSO4?
Ah, yes. I reversed it
Thank you!
Well, if you heat a hydrate, it's like playing hide-and-seek with the water molecules. You're literally "driving off" the water, like a chauffeur on a hot summer day. So, for every mole of CaSO4*2H2O (that's the fancy name for the hydrate), you'll be waving goodbye to 2 moles of water! It's like a magic trick, only without the rabbits.
To determine how many moles of water should be driven off per mole of CaSO4*2H2O hydrate when heated, we need to understand the chemical formula.
The formula CaSO4*2H2O indicates that one mole of the hydrate contains two moles of water molecules (H2O).
This means that for every mole of CaSO4*2H2O, two moles of water should be driven off when heated.
