What is the component of alcohol?

How do you calculate VV?
Calculating Percent Volume/Volume (% v/v)
- A percent v/v solution is calculated by the following formula using the milliliter as the base measure of volume (v):
- % v/v = mL of solute/100 mL of solution.
- Example:
- X % = 5.0 mL HCl/100 mL of solution.
- X/100 = 5.0/100.
- 100X = 500.
- X = 5.0% % v/v.
How do you convert VV to ethanol?
Example: when 52 ml pure ethanol is mixed with 48 ml of water a volume of 96.3 ml is obtained instead of 100 ml….Ethanol concentration table: what is the percentage by volume or weight?
| Concentration of ethanol by weight (w/w) | Concentration of ethanol by volume (v/v) |
|---|---|
| 54.1% (w/w) | 62.0% (v/v) |
| 60.0% (w/w) | 67.7% (v/v) |
| 61.0% (w/w) | 68.7% (v/v) |
