How do you find the percent of a solution?
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.
