A 10.00-g sample that contains an analyte is transferred to a 250-mL volumetric flask and diluted to volume. When a 10.00 mL aliquot of the resulting solution is diluted to 25 ml it gives a signal of 0.235 (arbitrary units). A second 10.00 mL portion of the solution is spiked with 10.00 mL of a 1.00-ppm standard solution of the analyze and diluted to 25.00 mL. The signal for the spiked sample is 0.502. Calculate the weight percent of analyte...
