Strategy:
 This redox reaction is solved by balancing the total number of electrons lost during oxidation with the total electrons gained during reduction. The mole ratio is derived directly from the balancing coefficients.

Step 1: Identify oxidation states and changes
- : Mn goes from  to  (Gains ).
- : S goes from  to  (Loses ).

Step 2: Balance the electrons
To balance  gained and  lost, we multiply the Mn reaction by 2 and the S reaction by 5.

Step 3: Determine the ratio per mole of sulph
