Calculate the solubility of carbon dioxide in water at 0 °C and a pressure of 3.00 atm. The solubility of carbon

dioxide is 0.348 g/100 mL water at 0 °C and 1.00 atm.

Dear student!

According to Henry's Law;

The solubility of carbon dioxide gas is proportional to the pressure of the gas above the liquid.

Solubility of gas at normal condition  × pressure factor =  new solubility of gas 

Since pressure increases, solubility increases, and the pressure factor is greater than one.

Here, pressure factor = 3.00atm/ 1.00atm = 3 

So,  solubility at increased pressure = 0.348gm/100ml  x 3 =  1.044 gm/100ml
