Consider a 100 mL aqueous standard solution containing 100 μg/L of iodomethane that is stored in a well sealed 1 L flask (i. e., 900. mL of air). The following data is provided for iodomethane;

Po = 53,700 Pa, Cw Sat = 0.0977 mol L-1, KH = 542 Pa m3 mol-1

a) Calculate the concentration of iodomethanein the water and headspace of the bottleat equilibrium at 25°C.

b) If the bottle is opened after equilibration and all of the air in the headspace is flushed out and replaced by fresh air, what will the concentration of iodomethane be in the aqueous solution after the equilibrium is re-established?

c) Calculate the fraction of iodomethane present in the liquid water of a cloud aerosol characterized by VH2O(l)= 0.10 mL per 100. L air. How will your answer change if the temperature is 5°C?
