$A$ metal chloride contains $49.5\%$ chlorine. The specific heat of the metal is $0.064 \ cal \ g^{-1} \ ^\circ C^{-1}$. What is the exact atomic weight of the metal?

The equivalent mass of a divalent metal is $31.82$. What is the mass of a single atom of this metal?

On what basis is the modern atomic mass standard defined?

If the equivalent mass of a metal with a valency of $+2$ is $12$,then the molar mass of its oxide is:

Suppose two elements $X$ and $Y$ combine to form two compounds $XY_{2}$ and $X_{2}Y_{3}$. If $0.05 \ mol$ of $XY_{2}$ weighs $5 \ g$ while $3.011 \times 10^{23}$ molecules of $X_{2}Y_{3}$ weighs $85 \ g$,then atomic masses of $X$ and $Y$ are respectively :

The equivalent weight of an acid:
