Cu2S→Cu2++SO32−\mathrm{Cu}_2 \mathrm{S} \rightarrow \mathrm{Cu}^{2+}+\mathrm{SO}_3^{2-}, if M\mathrm{M} is the molar mass of Cu2S\mathrm{Cu}_2 \mathrm{S}, then its equivalent mass is given as
View answer and explanation
Correct option: A
M8\frac{M}{8}
The correct answer is A (M/8) because the n-factor for Cu2S in the given reaction is 8, representing the total change in oxidation state.
