A soil analysis was done for the exchangeable cations in the soil and the results were as follows:Ca = 1.8 g/kg (atomic wt. Calcium is 40 g/mol)Mg = 3.25 cmolK = 3 cmolNa = 0.230 g/kg (atomic wt. of Na is 23 g/mol)H = 9 cmolAl= 0.66 cmol. Calculate the CEC of this soil (Do not forget the units). Please show example calculations.
