Canvas Classes · Accepted Answer

Strategy:
 Determine the -electron count from the oxidation state, find the number of unpaired electrons based on the ligand field, and calculate the magnetic moment.

Step 1: Determine the metal ion and configuration
In , let x be the oxidation state of Mn:
.
 has a  electron configuration.

Step 2: Determine unpaired electrons
Bromide () is a weak field ligand, resulting in a high-spin octahedral complex ().
Number of unpaired electrons () = 5.

Step 3: Calculate magnetic moment
.
Rounded to t
