TABLE 5.1 Solubility of Gases in Water
The column (or line entry) headed “				” gives the volume of gas (in milliliters) measured at standard conditions
(0 C and 760 mm or 101.325 kN · m				2 ) dissolved in 1 mL of water at the temperature stated (in degrees Celsius)
and when the pressure of the gas without that of the water vapor is 760 mm. The line entry “A” indicates the
same quantity except that the gas itself is at the uniform pressure of 760 mm when in equilibrium with water.
The column headed “1” gives the volume of the gas (in milliliters) dissolved in 1 mL of water when the
pressure of the gas plus that of the water vapor is 760 mm.
The column headed “q” gives the weight of gas (in grams) dissolved in 100 g of water when the pressure of
the gas plus that of the water vapor is 760 mm.
