AThe solute's volume against the solution's mass
BThe solute's mass against the solution's volume
CThe solute's mass against the solvent's volume
DThe solute's moles against the solution's volume
Answer & Solution
Correct answer: B. The solute's mass against the solution's volume
1. Mass-volume percent is a mixed unit built from two different kinds of measurement.
2. It is the ratio of the solute's mass to the solution's volume, expressed as a percentage.
3. The specific units may vary depending on the solution being described.
4. Comparing moles against volume gives molarity instead, not a mass-volume percent.
