Chloroform is used as an internal standard in the determination of the pesticide deltamethrin. To calibrate the method a mixture of 0.500 mM of chloroform and 0.800 mM of deltamethrin which produced signals of 15.3 (a.u.) and 10.1 (a.u.) for chloroform and deltamethrin, respectively. unknown deltamethrin and 10.10 µL of pure chloroform (FW = 119.39 g / mol, Peloroform = 1.484 g / L) To prepare the sample, place 10.00 mL of a conc sample, homogenize and dilute with water up to the mark of 100.00 mL in a volumetric flask. After preparing the sample, the observed signals of 30.0 (a.u.) and 20.7 (a.u.) for chloroform and deltamethrin, respectively. to. Determine the response factor (K) for the method. (3 pts.) B. Determine the millimolar concentration (mM) of chloroform added to the sample. Remember that the final volume of the solution is 100.00 mL. (3 pts.) C. Determine the millimolar (mM) concentration of deltamethrin in the sample. (3 pts.) D. If the deltamethrin concentration should not exceed 20.00 mM in drinking water. Determine whether or not the water sample that was tested is considered drinking water. Briefly explain your answer. (1 pt.)
