TABLE 202. 



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 

 gramme-molecules of the salt in a litre of water. The numbers in these columns give the lowering of the 

 vapor pressure produced by the salt at the temperature of boiling water under 76 centimetres barometnc pressure.
