In chlorine gas,the ratio of $Cl^{35}$ and $Cl^{37}$ is

$A$ metal oxide is reduced by heating it in a stream of hydrogen. It is found that after complete reduction,$3.15 \, g$ of the oxide yielded $1.05 \, g$ of the metal. We may deduce that:

The equivalent weight of a divalent metal is $W$. The molecular weight of its chloride is...

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

$A$ 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 $X$?

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 $= M$)
