Henry's law states that the concentration of a gas in a liquid is directly proportional to the partial pressure of that gas above the liquid. The formula for Henry's law is $C = kP$, where $C$ is the concentration of the gas in the liquid, $P$ is the partial pressure of the gas, and $k$ is Henry's law constant. Given $C = 1.2 \times 10^{-1}$ M and $P = 4.0$ atm, we can solve for $k$ as follows: $k = \frac{C}{P} = \frac{1.2 \times 10^{-1}}{4.0} = 3.0 \times 10^{-2}$ mol/L-atm.
