A student, Legna, massed out 10.12 g of chromium(III) chloride hexahydrate to synthesize a transition metal coordination complex similar to what you are carrying out in your laboratory synthetic effort but with a different metal. From her synthesis, like in part 1, she obtained 7.20 g of a complex containing Chromium, Cr, ammonia, NH3, and chlorine, Cl. Samples of this compound are used to perform all advanced study analyses for the remainder of the assignments. The following data were obtained. {To the student: Please note that the synthesis and analysis of the compound in this and the following advanced study assignments are similar to but not identical to your experimental syntheses and analysis project! Keep the results of your calculations from advanced study assignment 2, and 3 in your notebook so that you can complete advanced study assignment 4. Analysis 1. No heat applied Mass of compound used Mass of crucible plus AgCl Mass of crucible Mmass AgCl = 143.32 g/mol Mmass Cl = 35.45 g/mol 0.4988 g 19.2859 g 18.4628 g Analysis 2. Heat applied Mass of compound used Mass of crucible plus AgCl Mass of crucible 0.4632 g 21.0926 g 20.3286 g % (a) Determine the %CI in each sample of the compound. Show calculations below! Not heated _%, Heated
(b) Calculate the ratio of%Cl(heated analysis)/%Clunheated analysis).
(c) Which one of the Cl-analyses gives the total chloride in the complex, the heated or unheated analysis? (circle your answer) Briefly explain your reasoning.
