3. calculations (Note for ppm, it is volume ratio for gases, and mass ratio for liquid). 3.1 (2 points) The average concentration of chloroform (CHC) in a lake is 30 ng/L. The saturated water solubility of chloroform is 480 ppm, its vapor pressure is 30 Torr, and molecular weight is 119.4 g/mol. Assume a wind speed of 3 m/s, the temperature is 295 K, and its air concentration can be ignored. (you will need: 1 atm = 760 Torr, water density is 1 g/mL). Calculate the following: 3.1a. What's the unitless Henry's law constant? 3.1b. The overall exchange velocity (Viotai) of chloroform (in unit of cm/h)? 3.1c. The evaporative flux of chloroform from this lake (in unit of ng hom)? 3. calculations (Note for ppm, it is volume ratio for gases, and mass ratio for liquid). 3.1 (2 points) The average concentration of chloroform (CHC) in a lake is 30 ng/L.
