How do you calculate percent by volume?
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.
What does 70% vv mean?
vv%=volume of solutevolume of solution×100. So, returning to our rubbing alcohol, 70% (vv) means that for every 100 mL of solution, there are 70 mL of the solute, isopropanol. 70%=volume of solute100 mL×100. Volume of solute = 70 mL.
