What will be the mass of the solute in $g$ in $1 \, L$ of a solution having $40 \%$ concentration by weight? The density of the solution is $1.2 \, g/mL$.

Explain $\% \, w/V$ and $\% \, w/w$ in brief.

$x \ g$ of $NaCl$ is added to water in a beaker with a lid. The temperature of the system is raised from $1^{\circ}C$ to $25^{\circ}C$. Which out of the following plots is best suited for the change in the molarity $(M)$ of the solution with respect to temperature? [Consider the solubility of $NaCl$ remains unchanged over the temperature range]

$3.0$ molal $NaOH$ solution has a density of $1.110 \ g/mL$. The molarity of the solution is :-

Calculate the molarity if $30 \, mL$ of $0.5 \, M$ $H_2SO_4$ is diluted to $500 \, mL$. (in $, M$)

If the molality of an aqueous solution is $m$ and the mole fraction of the solute is $y$,which of the following relations is correct?
