Ratio (water:anhydrous residue)
mole ratio = moles of water/mole of anhydrous residue
Did you drive off all the water from the hydrate?
Don't ask Prof.
Kluiber. What does he know? Find out for yourself!
To find out.....
Reheat the the tube. Watch for any water being given off.
There should not be any!
Cool and reweigh.
If the two weights are the same, ± 1-2 mg, and no
water was given off, you probably dehydrated the hydrate properly.
