Question

Step 1. Procedure Obtain a weighted amount of the Copper (II) Sulfate hydrate (say 30 g), place in an 100 ml beaker Step 2. Heat compound with bunsen burner until all of the water is driven-off (you can verify this be weighing the beaker while heating it, when the weight stops declining you’ve removed all the water. Step 3. Weigh final compound.

write your observations

Observations:

Initial Weight:

Final Weight:

Weight of Water driven off (Initial weight - final weight) :

moles of water loss: Weight of water / GMW H2O (18.016 )
moles of CuSO4: final weight/ GMW CuSO4 (159.61)

X = moles of water loss/ moles of CuSO4

Given that hydrate is: CuSO4 (XH2O)

Formula of hydrate:

Explanation / Answer

Initial Weight: 30 grams or weight of Beaker with hydrated compound - weight of empty carbon

Final Weight: weight of the beaker - weight of beaker after after water driven off

Weight of Water driven off (Initial weight - final weight) :

weight of Beaker with hydrated compound - weight of beaker after after water driven off

moles of water loss: Weight of water / GMW H2O (18.016 )

weight of Beaker with hydrated compound - weight of beaker after after water driven off / GMW H2O (18.016 )

moles of CuSO4: final weight/ GMW CuSO4 (159.61)

weight of the beaker - weight of beaker after after water driven off / GMW CuSO4 (159.61)

if you give the empty beaker weight

we can get all these values but you did not give that value.
