$2 \ g$ of metal carbonate is neutralized completely by $100 \ mL$ of $0.1 \ N$ $HCl$. The equivalent weight of metal carbonate is:

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

Equivalent weights of $X_2Y$ and $X_2Y_3$ are $38$ and $18$ respectively. Find the atomic masses of $X$ and $Y$:-

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?

$A$ mixture of $1.65 \times 10^{21}$ molecules of $X$ and $1.85 \times 10^{21}$ molecules of $Y$ weighs $0.688 \ g$. If the molecular mass of $Y$ is $187 \ g/mol$,what is the molecular mass of $X$?

If a metal oxide contains $32\%$ oxygen,what is the equivalent mass of the metal?
