The specific heat of a metal is $0.031 \ cal \ g^{-1} \ ^\circ C^{-1}$ and its equivalent weight is $103.6$. What is the exact atomic weight of the metal?

Find out the equivalent mass of $KIO_{3}$ in the given reaction.
$2Cr(OH)_{3} + 4OH^{-} + KIO_{3} \to 2CrO_{4}^{2-} + 5H_{2}O + KI$
(Molecular Mass $= M$)

Elements $X$ and $Y$ form compounds $X_2Y_3$ and $X_3Y_4$ respectively. If $0.2 \ mol$ of $X_2Y_3$ weighs $32.0 \ g$ and $0.4 \ mol$ of $X_3Y_4$ weighs $92.8 \ g$,then the atomic masses of $X$ and $Y$ are respectively:

The present atomic weight scale is based on

What will be the mass of one atom of ${}^{12}C$?

The equivalent weight of a metal is $4.5$ and the molecular weight of its chloride is $80$. The atomic weight of the metal is
