The sum of the mole fraction of the components of a solution is

The strength of a solution $(S)$ in $g/L$ is related to its normality $(N)$ and equivalent weight $(E)$ of the solute by the formula:

Find out the molality of the solution formed by dissolving $29.22 \ g$ of $NaCl$ in $2.00 \ kg$ of water. (in $m$)

Calculate the density of an aqueous solution of $KI$,if its molarity and molality are $1.44 \ M$ and $1.5 \ mol \ kg^{-1}$ respectively. (in $g \ mL^{-1}$)

Molarity of $4\%$ $NaOH$ solution is ......... $M$.

The volumes of $4\,N\, HCl$ and $10\,N\, HCl$ required to make $1\, L$ of $6\,N\, HCl$ are
