The molality and molarity of a solution of glucose in water which is labelled as $10 \% (w/w)$ are respectively (density of solution $= 1.2 \ g \ mL^{-1}$)

If equal weights of $NaCl$ and $KCl$ are dissolved in the same volume of solution,how will the molarity of the two solutions compare?

The density of $NaOH$ solution is $1.2 \, g \, cm^{-3}$. The molality of this solution is $.... \, m$ (Round off to the nearest integer). [Use: Atomic masses: $Na: 23.0 \, u, O: 16.0 \, u, H: 1.0 \, u$]

Explain the concept of reactions in solutions and mass percentage.

Two solutions labelled as $3 \, M \, HCl$ and $1 \, M \, HCl$ are mixed in the ratio of $x : y$ by volume and the molarity of the resulting solution is $1.5 \, M$. What is the molarity of the resulting solution if they are mixed in the ratio $y : x$ by volume?

Calculate the molality of $2.5 \ g$ of ethanoic acid $(CH_{3}COOH)$ in $75 \ g$ of benzene.
