Which of the concentration ratios is most often used when both the solvent and the solute are liquids?

Question

a
percent by mass
b
percent by volume
c
molarity
d
molality

Answer 1

When both the solvent and the solute are liquids, the concentration ratio that is most often used is:

b) percent by volume.

Percent by volume is commonly used in such cases because it expresses the volume of the solute relative to the total volume of the solution, making it suitable for solutions where both components are liquids.
