Which of the following concentration factors changes with temperature?

Calculate the mass percentage of benzene $(C_{6}H_{6})$ and carbon tetrachloride $(CCl_{4})$ if $22 \ g$ of benzene is dissolved in $122 \ g$ of carbon tetrachloride.

If the mole fraction of the solute in benzene is $0.2$,then the molality of the solution will be ..............

Calculate the mole fraction of $C_2H_6O_2$ (ethylene glycol) in an aqueous solution containing $28 \%$ by mass of $C_2H_6O_2$.

The density of an aqueous solution of $4\%$ by mass $NaOH$ is $1.04\ g/mL$. The molality of the solution is:

To what extent must a given solution of concentration of $40 \, mg$ silver nitrate per $mL$ be diluted to yield a solution of concentration of $16 \, mg$ $AgNO_3$ per $mL$?
