Explain what was the au in the original sample

Reference no: EM13552337

A Solution was analyzed using AA spectroscopy for Au. The signal registered was 150. The sample solution was placed in a 10ml container and spiked with 2ml of a 0.125mM standard Au solution. The spiked solution returned a AA signal of 185. What was the [Au] in the original sample?
