A student, Legna, massed out 10.12 g of chromium(iii)chloride hexahydrate to synthesize a transition metal coordination complex. She obtained 7.20 g of a complex containing Chromium (Cr), Ammonia (NH3), and Chlorine (Cl). Samples of this compound were used to perform all analyses for the remainder of the advanced study assignment. The following data were obtained. analysis 1: no heat applied mass of compound used .4988g mass of crucible plus AgCl 19.2859g mass of crucible 18.4628g MM AgCl 143.32 g/mol MM...
