What does 0.1 v/v mean?
In chemical notation, "v/v" is an abbreviation for "volume per volume". It is a unit of measurement that expresses the concentration of a solution, indicating the ratio of the volume of a solute to the volume of the total solution.
Breaking down the notation
In the notation "0.1 v/v", there are two parts:
- 0.1: This represents the ratio of the volume of the solute to the volume of the total solution. In this case, it means that for every 1 unit of volume of the solution, 0.1 units of volume are solute.
- v/v: This indicates that the ratio is a volume per volume measurement.
Practical application
To illustrate, let's say you have a solution of ethanol in water, and the concentration is 0.1 v/v. This means that for every 100 mL of the solution, 10 mL are ethanol and 90 mL are water.
Conversion to other units
0.1 v/v is equivalent to other units of measurement, such as:
- Percentage (%): 10%
- Parts per hundred (pph): 10 pph
- Molarity (M): 0.1 M (approximately)
Conclusion
In summary, 0.1 v/v is a concentration unit that represents a ratio of 1 part solute to 10 parts solution. It is commonly used in chemical notation to express the concentration of a solution.
