Asked by Jake
If 2.64g of CO2 dissolves in 500ml water at 25°C, what is the Kh(Henry's law constant) for CO2? The total pressure is 3340 mmHg and air pressure at 25°C is 680 torr.

I would be better if you used the same screen name.
Apparently there is no standard Kh. I will use the one that is
p = Kc*C but C = K*pgas is also used.
p is 3340-680 mm. Convert to atm.
Kc is the constant.
C is the molarity. You will want mols = grams/molarmass and M = mols/L. Substitute and solve for Kc. K in one equation is the reciprocal of that in the other equation. The units for the one I've used is L*atm/mol.
