Answer:
The correct answer is option false.
Explanation:
Molality of the solution defined as moles of substance present in 1 kilogram of solvent.
Moles = [tex]\frac{Mass of solute}}{\text{molar mass of solute}}[/tex]
[tex]Molality=\frac{Moles}{\text{Mass of solvent(kg)}}[/tex]
Mass of percent (w/w%) of the solution is defined as amount of solute present in 100 grams of solution.
[tex](w/w\%)_=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times 100[/tex]
So, if want to inter-convert molality into mass percent we can do that without knowing density of solution.
Mass of solution = Mass of solute + Mass of solvent
