The Henry's Law constant for carbon dioxide gas in water at 25 oC is 0.031 mol/L-atm. Calculate the solubility of carbon dioxide in water at 25 oC in moles/L if the partial pressure of carbon dioxide in the headspace above a water sample is 1.68 atm.
a) The solubility is 0.0521 M.
b) The solubility is 0.182 M.
c) The solubility is 0.0185 M.
d) The solubility is 54.2 M.
e) The solubility is 15.5 M.
