I have a few liquids and I want to determine the solubility of CO2 in each of these liquids. How can I set up an experiment to do so?

Put the liquids through a CO2 environment and weigh the difference?
Set up an upside-down glass tube (like a mercury barometer) with a CO2 bubble and see how it shrinks?

Not sure what to do, would appreciate some suggestions. Thanks!
