The following data were obtained when a test tube containing barium chloride hydrate was weighed before and after heating. The heating process drove off the water that was in the sample, producing an anhydrous salt. a) Mass of an empty test tube = 18.42g b) Mass of the test tube containing hydrate (before heating) = 20.75; c) Mass of the test tube containing anhydrous salt (after heating) = 20.41g The general formula of barium chloride is BaCl2 · nH2O, where n is the number of water molecules. The hydrate described by the data above either has a value of n=1; n=2; or n =3. Calculate the mass percent of water for each of these possible values of n

Question
The following data were obtained when a test tube containing barium chloride hydrate was weighed before and after heating. The heating process drove off the water that was in the sample, producing an anhydrous salt.
a) Mass of an empty test tube = 18.42g
b) Mass of the test tube containing hydrate (before heating) = 20.75;
c) Mass of the test tube containing anhydrous salt (after heating) = 20.41g
- The general formula of barium chloride is BaCl2 · nH2O, where n is the number of water molecules. The hydrate described by the data above either has a value of n=1; n=2; or n =3.
Calculate the mass percent of water for each of these possible values of n
