Explain the spiked solution returned a signal

Reference no: EM13551114

A solution was analyzed using AA spec for Au. The signal was 150. This sample solution was placed in a 10 mL container and spiked with 2 mL of a 0.125 mM standard Au solution. The spiked solution returned a signal of 185. What was the concentration of Au in the original sample
