mass of evaporating dish 22.34

mass of evaporating dish +hydrate 24.64
mass of evaporating dish +anhydrous salt 23.85
CuS04XH2O=CuSO4+XH2O
1.determine the mass of the water lost
2.determine the number of moles of the water lost

1 answer

24.64g = dish + hydrate
22.34g = dish
---------
2.30g = mass hydrate

24.64g = dish + hydrate
23.85g = dish + anhydrous
----------
0.79g = mass H2O lost

mols = grams/molar mass
