Question 8 6 Points Question 8: (6 points) 8.1.(4 points) Describe the preparation of two standard solutions that have 450 ppm of Nat in 250 mL volumetric flask and another one with 300 ppm of K* in 100 ml volumetric flask from primary standard of sodium chloride and potassium chloride respectively. (MM of Na = 23 g/mol, MM of K = 39.1 g/mol, MM of CI = 35.45g/mol). Please show all your calculation to get full credits. 8.2. (2 points) Use the above standard solutions to prepare 100 mL of one standard solution that contains 45.0 ppm Nat and 35.0 ppm Kt in the same volumetric flask.
