The correct answer is:
10
\(\begin{aligned}
& a \stackrel{+3}{\mathrm{C}_2} \mathrm{O}_4^{2-}+b \stackrel{+7}{\mathrm{M}} \mathrm{O}_4^{-}+\mathrm{H}^{+} \rightarrow p \stackrel{+4}{\mathrm{CO}_2}+q \mathrm{Mn}^{2+}+\mathrm{H}_2 \mathrm{O} \\
& \text {nf }(4-3) \times 2=2(7-2) \times 1=5 \\
& \text {mole: } \quad 5 \\
\end{aligned}\)
\(\Rightarrow \quad a=5, b=2\)
\(\Rightarrow\) By POAC, for C-atoms: \(2 a=p\)
\(p=2 a=2 \times 5=10\)
(Here, \(n f: n\)-factor or valency factor)
