  1. Mass-volume percent is often abbreviated as % m/v.
  2. It is commonly used in medical and laboratory settings to describe concentrations of solutions.
  3. The formula for mass-volume percent is: $\% m/v = \left( \frac{\text{mass of solute (g)}}{\text{volume of solution (mL)}} \right) \times 100$.
  4. Unlike molarity, mass-volume percent does not depend on temperature because it uses mass and volume directly.
  5. A 10% m/v NaCl solution means there are 10 grams of NaCl in every 100 mL of solution.
