In a preliminary experiment, a solution containing 0.0837 m x and 0.0666 m s gave peak areas of ax = 423 and as = 347. (areas are measured in arbitrary units.) to analyze the unknown, 10.0 ml of 0.146 m s were added to a flask with 10.0 ml of unknown and the mixture was diluted to 25.0 ml in a volumetric flask. this mixture gave ax = 553 and as = 582. find the concentration of x in the unknown.
1) find the value of f determined in the preliminary experiment. report your answer to 3 significant figures.
2) find the value of [s]final. report your answer in m to 3 significant figures.
3)find the value of [x]final. report your answer in m to 3 significant figures.
