(b) from (a) obtain the aqueous solubility of the compound;

(d) using data from (b) and (c) obtain the Henry's constant, expressed in dimensionless molar ratio; and

(e) a wastewater stream of 100 m² and a depth of 1 m is contaminated with the compound at a concentration of 1μg/L. A measurement of flux to air showed 10μg in a chemical trap obtained in 1 h of sampling. What is the concentration of the chemical in ambient air above the stream? Note that the individual water- and air-side mass transfer coefficients for the chemical are 1 × 10^-5 m/s and 0.005 m/s, respectively
