A soil test indicates that the soil contains 412 ppm of potassium, 118 ppm of magnesium, 1450 ppm of calcium, and 35 ppm of sodium, with a pH of 7.6. Since the pH is above 7.0, no hydrogen ions are reported. Based on this information, calculate the Cation Exchange Capacity (CEC) of the soil in meq/100 g soil., 9.41 meq/100 g, 14.2 meq/100 g, 18.6 meq/100 g, 22.4 meq/100 g
