1. The problem statement, all variables and given/known data[/b]
Given:
C2CL4 + Fe \rightarrow C2H4 + CL- + Fe2+
A reservoir contains 5million gallons of water which is contaminated with 4.2mg/L of Perchloroethene(C2CL4). You want too reduce it to harmless ethene(C2H4) by reacting it with Fe. because of this only about 20g of the added Fe is reactive. If you need to treat 5million gallons of water, how many grams of Fe will you need to treat the Perchloroethene(PCE)?
2. Relevant equations
I first balanced the equation
C2CL4 + 4H+ + 4Fe \rightarrow C2H4 + 4CL- + 4Fe^2+
Concentration of PCE=4.2mg/L
5mill gallons of water = 1.89 x 10^7 L
I do not know where to go from here
