According to literature, the solubility of CO2 in water is approximately 1500 ppm. Maybe, this means that no matter how much flow rate of CO2 into the open chamber filled with water, the concentration of CO2 in water does not exceed 1500 ppm. Then, if I flow CO2 gas at 1 cc/min mix with Air flow at 1 cc/min into the open chamber filled with water, meaning that the flow ratio of CO2 : Air is 1 : 1, what will the concentration of CO2 in water? (1/2)x1500 ppm? Is this right?
The CO2 concentration in solution must be related to its partial pressure and there should be plenty of data from industrial processes such as the carbonation of drinks
There are easy gas conversion calculators on the web you can use, or you can make a quick, approximate conversion (assuming 77 degrees F and sea level or 25°C) for CO2 only by multiplying the ppm by 1.808 to get mg/m³ or dividing mg/m³ by 1.808 to get ppm.

Jin.... The solubility of CO2 in water can be increased by pressure as may be the case in beverages. Further, CO2 is higher in density than air and hence the 1 cc /min is not simply directly reflects the conc. it represents 1.977 mg/min at 1.0 atm. You can proceed from such figures to get your right answer .... Good luck
