WebAccording to Henry’s law, for an ideal solution the solubility, Cg, of a gas (1.38 × 10 −3 mol L −1, in this case) is directly proportional to the pressure, Pg, of the undissolved gas above the solution (101.3 kPa, or 760 torr, in this case). Because we know both Cg and Pg, we can rearrange this expression to solve for k. Web1,2-Dibromoethane, also known as ethylene dibromide ( EDB ), is an organobromine compound with the chemical formula C 2H 4Br 2. Although trace amounts occur naturally in the ocean, where it is formed probably by algae and kelp, it is mainly synthetic.
