Where does all the water go? According to the Environmental Protection Agency (EPA), in a typical wetland environment, 38% of the water is outflow; 47% is seepage; 7% evaporates; and 8% remains as water volume in the ecosystem.+ Chloride compounds as residuals from residential areas are a problem for wetlands. Suppose that in a particular wetland environment the following concentrations (mg/L) of chloride compounds were found: outflow, 74.0; seepage, 75.7; remaining due to evaporation, 50.2; in the water volume, 70.6. (a) Compute the weighted average of chlorine compound concentration (mg/L) for this ecological system. (Round your answer to one decimal place.) x mg/L
