Suppose that in a particular wetland environment the following concentrations (mg/l) of
chloride compounds were found:
outflow 64.1, seepage 75.8, remaining due to evaporation 23.9, in the
water volume 68.2.
Compute the weighted average of chlorine compound concentration in milligrams per liter (mg/l) for
this ecological system.
