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

$5 \, mol$ of $AB_2$ weigh $125 \times 10^{-3} \, kg$ and $10 \, mol$ of $A_2B_2$ weigh $300 \times 10^{-3} \, kg$. The molar mass of $A$ $(M_A)$ and molar mass of $B$ $(M_B)$ in $kg \, mol^{-1}$ are:

If $A_1 \ g$ of an element gives $A_2 \ g$ of its oxide,then the equivalent mass of the element is .....

What is the mass in gram of $1$ atom of an element if its atomic mass is $10 \ u$?

Which one of the following properties of an element is not variable?

The equivalent weight of a divalent metal is $32.7$. The molecular weight of its chloride is .....
