The following data were collected from the gravimetric analysis of a hydrated salt:?
The following data were collected during a gravimetric analysis of a hydrated salt:
- Mass of crucible and lid: 19.437 g
- Mass of crucible, lid, and hydrated salt: 21.626 g
- Mass of crucible, lid, and anhydrous salt: 21.441 g
Calculate the percentage of water in the hydrated salt.

its simple mathematical problem.
mass of the hydrated salt will be 21.626-19.437= 2.189g
mass of anhydrous salt Will be 21.441- 19.437 = 2.004g
mass of the water will be 2.189-2.004 = 0.185
% of water in the substance can be found by dividing it by mass of hydrated salt
i.e (0.185/2.189) x 100= 8.45%
