An enzyme peroxidase has $5\%$ by weight of sulphur $(S = 32)$. Its minimum molecular weight will be:

Statement $1$: The equivalent mass of $Cu$ in $CuO$ is $63.6$ and in $Cu_2O$ is $31.8$. Statement $2$: Equivalent mass = $\frac{\text{Molecular mass}}{\text{Valency}}$

The equivalent weight of potassium permanganate $(KMnO_4)$ in an acidic solution is:

In chlorine gas,the ratio of $Cl^{35}$ and $Cl^{37}$ is

Which of the following statements is not true about atomic mass?

If $m_1 \ g$ of metal $A$ displaces $m_2 \ g$ of another metal $B$ from its salt solution,and their equivalent weights are $E_1$ and $E_2$ respectively,how is the equivalent weight of $A$ expressed?
