Question 2 Zinc was analysed in acid mine drainage (AMD). The signal obtained from an AAS for the sample was 0.125 absorbance units. 25.00 mL of a 0.15 ppm Zn standard was added to 75.00 mL of the sample. The signal obtained was 0.750. a. The 0.15 M Zn standard of volume 500 mL was prepared from zinc (II) phosphate. Determine the mass of salt required to make the standard. 4.43 x 10 g b. Determine the Zn concentration in the AMD sample. [Zn] 0.00619 ppm
