2. The aqueous solubility of toluene (C7H8) at 25C is 515 mg/L. A water sample contained within an EPA sampling vial is in equilibrium with the vial's headspace at a temperature of 25C The vapor phase within the headspace is analyzed using a GC and shown to contain 6.7 mg/L of toluene. Determine the aqueous phase concentration of the toluene in units of mg/L

explanation:  

an electrode is a metal whose surface serves as the location where oxidation-reduction equilibrium is established between the metal and what is in the solution.

answer:

design model: consists of design geometry; can be 2d or 3d; typically has a black background.

design files: drawing created with microsoft expression design, a drawing and design program for windows; may contain both vector and raster graphics; can also include multiple layers and various image effects.

elements: an element is a single part of a larger group.
