Which method of expressing the concentration of a solution is independent of temperature?

The molarity of pure water is $......$

What is meant by the concentration of a solution?

The correct relationship between molality $(m)$ and molarity $(M)$ of a solution is ($d = $ density in $g/mL$ and $M_{solute} = $ molar mass of solute in $g/mol$)

The molality of an aqueous solution of any solute having a mole fraction of $0.25$ is . . . . . . . (in $m$)

Calculate the mass fraction and mass percentage of aspirin in a solution prepared by dissolving $3.65 \, g$ of aspirin in $25.08 \, g$ of water.
