answer with the correct number of significant figures but without "%" (Canvas will not let you to enter units in this problem). 2) What is the theoretical mass % of water in the hydrate if the salt is BaCl2 x 2H2O? Make sure you use enough significant figures for the atomic weights of the elements and round your answer to 3 decimals. 3) What is the mass of the hydrate placed in the crucible? 4) What is the mass of the anhydrous salt?
The mass of preheated crucible with cover was 12.1125 g. After the hydrate sample was added, the weight increased to 13.1533 g. After heating the crucible for three times in order to remove hydrate water and bring it to the constant weight the lowest of the three mass measurements was 12.9971 g.
