(5pt) The molar absorptivity for cobalt and nickel complexes with 2,3-quinoxalinedithiol are 3.64104 L/Mcm for Co at 510nm and 5.52103L/Mcm and 1.24103I/Mcm for Co at 656nm and 1.75104 L/M-cm for Ni. A 250mg soil sample is collected near an industrial metal-processing plant is dissolved, masking agent added to avoid interference from other metals present. Color is developed by adding the complexing agent and the sample is diluted to 100.0ml. The absorbance at 510nm is 0.517 and at 656nm is 0.405 in a 1.0cm cell. Calculate the weight percent Co and Ni in the soil
