Henry's law states that the solubility of a gas is directly proportional to its partial pressure, LaTeX: S_g=k/cdot P_gS g = k ⋅ P g, where Sg is the solubility of the gas, Pg is the partial pressure of the gas, and k is the Henry's law constant for a specific gas at a specified temperature. What is the millimolar solubility of oxygen when the atmospheric pressure is 705 mmHg? Air is composed of 21% oxygen by moles. The Henry's law constant for oxygen is 1.3x10-3 mol/L-atm.

Enter your answer numerically in units of mM to three significant figures.
