2) A student measured the magnetic susceptibility of a transition metal complex using the same MSB instrument used in this laboratory experiment. A mass of 0.163 grams of the compound with a molar mass of 445 g/mol was transferred into an MSB tube to produce a sample length (L) of 1.74 cm. The net magnetic susceptibility reading (R) of 2304.0 nerg·G–2·cm–1 was measured at 25°C. a) Calculate the molar magnetic susceptibility, χm, in erg·G–2·mol–1. b) Calculate the magnetic moment-Bohr magneton...

3. (5 pts.) The oxidation of copper metal by iron (III) chloride used in the etching of circuit boards goes as follows: 2 Fe3+ (aq) + Cu(s) → 2 Fe2+ (aq) + Cu2+ (aq) The reduction potential for the Fe3+/Fe2+ and Cu2+/Cu pair are +0.772 V and -0.340 V, respectively. The concentrations are [Fe3+] = 1.24 M, [Fe2+] = 248 M, and [Cu2+] = .342 M. The electrical potential for this cell at 25.00C is: (a) +1.057 V (b) +0.380...
