Recall that the solubility of a gas is given by Henry’s law:
Molar mass of C2H2Cl2 = 96.94 g/mol
6.705 x 10-6 mol/ L
A river is contaminated with 0.65 mg/L of dichloroethylene (C2H2Cl2). What is the concentration (in ng/L) of dichloroethylene at 21°C in the air breathed by a person swimming in the river (kH for C2H2Cl2 in water is 0.033 mol/L·atm)?
