Hi Dear

Because of CO2 has more solubility than Ar

Thank you sir for your reply.

My exact question is how many times is Ar less soluble than CO2. How to calculate that if we are not given any data. We could use Henry's Law only if we are given partial pressure and other things. But since in the question itself nothing is given how to get that value is my question, sir.

Outside my field, but the comparison must be made under conditions acidic enough so that only CO2 is present, unless there is some smart modelling
