Question 6

If your exchangeable Na⁺ concentration in the soil is 224 µg g^-1 soil and the CEC of your soil is 18 cmol_c kg^-1 soil, what % of the CEC is occupied by Na⁺?

a. 19.87

b. 1.27

c. 5.41

d. 20.33

e. 15.34

Answer 1

% of the CEC is occupied by Na⁺ = 5.41% (c)

First we converted the give Na⁺ conventration to the same unit in which CEC of soil is given in the question then we fount the percentage.
