the method of standard additions was used to determine nitrite in a soil ample. an aliquot of 1.00 mL of the sample was mixed with 24.00 mL of a colorimetric reagent, and the nitrite was converted to a colored product with an absorbance of 0.300. A blank solution gave a signal of 0.020. To 50.00 mL of the original sample containing the colorimentric reagent, 1.00 mL of a standard solution of 1.00*10^(-3) M nitrite was added and the new absorbance was 0.530. What was the concentration of the nitrite in the original undiluted sample?
