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:**

What is the % v/v of a solution that has 5.0 mL of hydrochloric acid (HCl) diluted to 100 mL with deionized water?

**X**% = 5.0 mL HCl/100 mL of solution

**X**/100 = 5.0/100

Cross multiplying,

100

**X**= 500**X = 5.0% % v/v**
