Please Answer: CALCULATION QUESTION 1 (A) Calculate the number of cmol of Al3+ cations needed to replace 10 cmolc of Ca2+ by cation exchange in a soil. (B) How many grams of Al3+ does this correspond to? (you’ll need the atomic weight of Al, which is 27 g/mol, to calculate this) CALCULATION QUESTION 2 A soil sample (500 g) contains the following amounts of exchangeable cations: Ca2+= 9 cmolc , Mg2+= 3 cmolc , K+= 1 cmolc , Al3+= 3...
