Are henry's constant and ostwald solubility coefficient same? can we calculate the dissolved concentration of gas in water at equillibrium with the atmosphere using gas concentration of ambient air and henry,s law. If so, how do we calculate henry's constant for that system using temperature and pressure values, to use this in henry's equation. Also a another term Bunsen coefficient.

For reference (that is making me confused):

In a paper, they have given the defination for:

Ostwald solubility coefficient as:

The volume of gas (at a given temperature and pressure) dissolved per unit volume of solvent.

Bunsen coefficient:

the volume of gas at standard temperature and pressure (STP), dissolved in a unit volume of solution at the temperature (T; degrees Kelvin) when the total pressure and fugacity are 1 atm. The Ostwald solubility coefficient is related to the Bunsen coefficient.

Ostwald coefficent= bunsen coefficient (T/T0)

T and T0 is temperature of water and standard temperature 273.15K
