TABLE 369.— VAPOR PRESSURE OF SOLUTIONS OF SALTS IN WATER 



The first column gives the chemical formula of the salt. The headings of the other 

 columns give the number of gram-molecules of the salt in a liter of water. The numbers 

 in these columns give the lowering of the vapor pressure produced by the salt at the tem- 

 perature of boiling water under 76 cmHg.
