TABLE 292.— DENSITY OF AQUEOUS SOLUTIONS 



The following table gives the density of solutions of various salts in water. The numbers 



give the weight in g/cm 3 . For brevity the substance is indicated by formula only. 



Weight of the dissolved substance in 100 parts by weight of 



the solution gy.
