170048 10% Se Soil Mixture Analysis

Sample 170048 was a 10% mixture of selenium and soil. The mass of the inner selenium is 0.5145g, while the mass of the outer selenium is 0.1245g. The method used was the thin window analysis method as explained here LB Thesis Thin Window Analysis. Below is a table of values to continue with the analysis of the selenium soil mixture:
