You obtained the following results on a water sample from a local lake; all units are in mg/L except pH (no units) and SC ( S/cm): Note: SC = specific conductance. Perform the following calculations: 1. Convert the given concentrations to mol/L and meq/L. Eq/L is that case corresponds to the number of moles of charges. 2. Calculate an ion balance ( cations - anions, in meq/L). What is the likely cause of any observed imbalance? 3. Convert the bicarbonate data to mg/L as CaCO3 and the ammonium and nitrate data to mg/L as N
