When an ion absorbs $6 \times 10^{20}$ electrons,it gets reduced. What is the number of gram equivalents of the ion?

The equivalent weight of an element is $4$. Its chloride has a $V.D$ of $59.25$. Then the valency of the element is:

The vapour density of the methyl ester of an organic monocarboxylic acid is $37$. What is the molecular weight of the acid?

The equivalent weight of a divalent metal is $31.82$. The weight of one atom of this metal is:

Atoms consist of protons,neutrons,and electrons. If the mass of neutrons were made half and the mass of electrons were made two times their actual masses,then the atomic mass of $_6C^{12}$ would:

An oxide of an element contains $67.67\%$ oxygen and the vapour density of its volatile chloride is $79$. What is the atomic weight of the element?
