The ratio of 'mass by volume percentage' to 'volume by volume percentage' of a given solution gives ______.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. density of solute.
The ratio of mass by volume percentage (w/v%) to volume by volume percentage (v/v%) of a given solution gives the density of the solute (or sometimes of the solution, depending on context). This is because mass by volume percentage is defined as mass of solute per 100 mL of solution, while volume by volume percentage is volume of solute per 100 mL of solution. Their ratio cancels the volume factor and directly relates mass to volume, which is density.
