Determine the elemental concentration of N, K, and Mg in the Complete (Control) nutrient solution used in Lab 5 in both ppm and Molar concentration

(4) Determine the elemental concentration of N, K, and Mg in the Complete (Control) nutrient solution used in Lab 5 in both ppm and Molar concentration (0 .5 marks each , 3 marks total ). The information in Table 5.1 is needed to perform these calculations. As a frame of reference, the elemental concentration of N, P, K, Ca, Mg, and S in the Complete solution ranges between 1-15 mM, and 31-235 ppm. Show ALL calculations for full marks. (Hint: See Appendix 5.1 for information on performing these calculations) (5) (i) Calculate the EC of the Complete nutrient solution using the following equation: EC = total ppm ionsf?00 (2 marks total) . When performing this calculation, the FeEDTA and micronutrient solutions can be disregarded, since these nutrients are present in low concentrations that have little impact on the EC. Show ALL calculations for full marks. (Hint: See Appendix 5.2 for information on performing these calculations; the answer should be close to the actual EC measured using the EC meter).
