A solution containing 3.47mM X (analyte) and 1.72 mM S (standard) gave peak areas of 3473 and 10222, respectively, in a chromatographic analysis. Then 1.00ml of 8.47mM S was added to 5.00ml of unknown X, and the mixture was diluted to 10.0ml. This solution gave peak areas of 5428 and 4431 for X and S, respectively.
a. Calculate the response factors for the analyte.b. Find the concentration of S (mM) in the 10.0ml of mixed solutionc. Find the concentration of X (mM) in the 10.0ml of mixed solutiond. Find the concentration of X in the original unknown
