Short answer:

If water is the solvent and the temperature and pressure are near normal (1 atmosphere pressure, 77 F or 25C temperature) then CO2 is about 25 times more soluble than O2 on a volumetric basis and 40 times as soluble on a mass basis.

Detailed answer:

You question should be more specific since the solubility of a gas in another substance depends on what that substance is, what the temperature of the system is and what the pressure of the gas is.

However, if I assume that the solvent is pure water, that the temperature of the system is about room temperature (25C or 77F) and that the pressure is 1 atmosphere then a calculation is possible using Henry's Law:

P = K * X

where

P is the partial pressure of the gas

K is the Henry's Law constant

X is the molar concentration of gas in the liquid (in Moles/Liter)

For some gases, like CO2, the Henry's Law constant will vary greatly with temperature making the calculation more complex. Most gases also deviate slightly from ideal Henry's law behavior when the concentration becomes large or the pressures extreme.

In the textbook "Physical Chemistry 3rd Edition" by P.W. Atkins on pg 168 the Henry's law constant for O2 at 298 K (25C or 77F) is given as 3.3 x 10^7 Torr while CO2 is given as 1.25 x 10^6 Torr. If we assume pure gas at atmospheric pressure (equal to 760 Torr) and calculate X we get

CO2: X = P/K = 760/1.25*10^6 = 0.000608 (6.08e-4) moles CO2 / liter water

That works out to 0.02918 grams per liter of water

O2: X = P/K = 760/3.3*10^7 = 0.000023036.08 (2.304e-5) moles O2 / liter of water

That works out to 0.000737 grams per liter of water

So at atmospheric pressure with a pure water solvent at 77 F (25 C) carbon dioxide is 26.4 times as soluble on a volumetric basis (liters of solute per liter of water) or 39.6 times as soluble on a mass basis (grams of solute per liter of water)

Which gas law explains why there is as much CO2 exchanged between the alveoli and blood as there is O2 exchanged despite the fact that the partial pressure difference is so much smaller for CO2?

Henry's Law explains that the amount of gas dissolved in a liquid is directly proportional to the partial pressure of that gas above the liquid. As CO2 is more soluble in blood than O2, even though the partial pressure difference is smaller for CO2, more CO2 can be exchanged between the alveoli and blood due to its higher solubility.


Is oxygenated water less dense than carbonated water?

I would think so. Oxygen is lighter than CO2. The solubility of CO2 is also higher than O2 in water, so there can be more of it in the water.

Why does more CO2 than o2 dissolve in liquid when both gases are at the same pressure?

This is due to differences in solubility between CO2 and O2 in the liquid. CO2 is more soluble in liquid compared to O2, so more CO2 molecules dissolve than O2 molecules when both are at the same pressure. This difference in solubility is attributed to the chemical nature of the gases and the liquid being dissolved in.

How is CO2 more diffusable than O2?

CO2 is more diffusible than O2 because it is more soluble in water and has a higher molecular weight, allowing it to move more readily across cell membranes and tissues. CO2 also has a higher partial pressure gradient than O2, which drives its diffusion from tissues to the lungs for elimination.
