# Crystal water

The chemist wanted to check the content of water of crystallization of chromic potassium alum K

How many crystal water instead of 24 molecules contain salt?

Additional data to compute:

M (K

M(K

_{2}SO_{4}* Cr_{2}(SO_{4}) 3 * 24 H_{2}O, which was a long time in the laboratory. From 96.8 g of K_{2}SO_{4}* Cr_{2}(SO_{4}) 3 * 24 H_{2}O prepared 979 cm^{3}solution of base. Subsequently, the 293 cm^{3}of the stock solution, a solution of barium nitrate, and a precipitate precipitated weighing 19.6 g.How many crystal water instead of 24 molecules contain salt?
