Below is my question about concentrations in gases and liquids. I understand Henry's Law and how it relates to partial pressures and can described the concentrations of gases and liquids, but I don't know where to start this problem. How much of the 10 ug goes into the gas or the liquid. Once I get one, I know I can get the other........

Questions: Investigators are concerned with the properties of some organic compounds, and have given you a
sample. The sample is placed in a well-sealed 1-L flask containing 100 mL of distilled water, 900 mL of
air.
Some of the properties of these substances are as follows:
Chlorobenzene; Fluorene
Molecular Weight 112.56; 166.22
Henry's Law Constant (mol/atm liter) 0.27; 12
Solubility (mg/l) 472; 1.99
Vapor Pressure (mm Hg) 11.7; 0.003
Density (gm/cm3) 1.11; 1.202
a. First, consider the case in which 10 micrograms of chlorobenzene are placed in the flask. If there
is 900 mL of head space, determine the concentrations of chlorobenzene that end up in the water
and air.Please provide the concentrations in micrograms per liter.
b. Next, consider the case in which 10 micrograms of fluorine is placed in the flask. Determine the
masses of fluorene that end up in the water and air. Please provide the concentrations in
micrograms per liter.
c. Please explain any differences (or similarities) you see in the properties of the two substances.
