#### Explanation:

A solution's **volume by volume percent concentration**, **for every** **of solution**.

In other words, the volume by volume percent concentration tells you how many milliliters of solute you would have if you were to pick a

In your case, you know that the solution has a **every**

Now, solutions are homogeneous mixtures, which means that the same the same composition throughout. This allows you to use the percent concentration as a **conversion factor** to determine how many milliliters of hydrogen peroxide you'd get in

#348 color(red)(cancel(color(black)("mL solution"))) * overbrace(("3.0 mL H"_2"O"_2)/(100color(red)(cancel(color(black)("mL solution")))))^(color(blue)("= 3.0% v/v")) = "10.44 g H"_2"O"_2#

The answer must be rounded to two **sig figs**, the number of sig figs you have for the percent concentration.

Therefore, you will have

#color(darkgreen)(ul(color(black)("volume H"_ 2"O"_ 2 = "10. mL")))#

**10.44mL**

#### Explanation:

The antiseptic **3.0% (v/v)**. This means that for every **100mL** of the antiseptic solution, you have **3mL** of the solute,

**3% (v/v)** is the same thing as writing as

If for every **100mL of soln** you have **3mL** of **348 mL** you would have:

**Answer: 10.44mL**
