The molar solubility of carbon dioxide gas is .

Explanation:

Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.

To calculate the molar solubility, we use the equation given by Henry's law, which is:

where,

= Henry's constant =

= partial pressure of carbonated drink

where = p = Total pressure = 0.400 atm

= mole fraction of

Putting values in above equation, we get:

Hence, the molar solubility of carbon dioxide gas is .
