1. from table 4 (along with the dilution factor and the weight of the soil sample) to calculate the mg of zincig soil in each control sample. Then determine the \%recovery of Zn from the control sample. Table 5: Percent recovery for Z n extraction of the control Calculate me of n tound in sol sample Calculate the Zn mg/g of soil sample Calcuate % recovery 1. Use the data from table 4 (along with the dilution factor and the weight of the soil sample) to calculate the 7nmg/gsoilincachunknownsample. Table 6: Concentration of Zn in the unknown soil 1. Use the data from table 4 (along with the dilution factor and the weight of the soil sample) to calculate the Zn mgig soil in each unknown sample. Table 6: Concentration of Zn in the unknown soil Calculate mg of Zn found in sail sample Calculate the 2nmg/g of soil sample Question: Using the average control \%recovery from table 5 and the average 7nmg/g for the unknown from table 6 . Perform a correction to determine the actual expected 7n mg/g of soil for the unknown. a sample calculation
