If the molecular mass and atomic mass of sulphur are $256$ and $32$ respectively,its atomicity is:

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

What do you mean by molar weight?

The specific heat of a metal is $0.16$,its approximate atomic weight would be

On reduction with hydrogen,$3.6 \, g$ of an oxide of a metal left $3.2 \, g$ of metal. If the equivalent weight of the metal is $32$,the simplest formula of the oxide would be:

Atoms or groups of atoms which are electrically charged are known as:
