10ml of alcohol dissolve in 90ml of water unit of concentration used is________________?
Correct answer: C. % v/v
- A. % w/w
- B. % w/v
- C. % v/v
- D. % v/w
Explanation
Both the alcohol and water amounts are measured as volumes, so the concentration is expressed as volume by volume, or % v/v. The likely mistake is choosing % w/w, which applies when both quantities are measured by mass.

About Properties of Liquids
Liquid behavior depends on intermolecular forces, which produce surface tension, viscosity, capillary action and a definite volume without a fixed shape. The topic also covers vapor pressure, evaporation, boiling point and the effect of temperature and external pressure, while distinguishing evaporation at the surface from boiling throughout the liquid.
