Answer:
Percent Volume
The concentration of a substance can be expressed in several quantities such as moles, percent (%) weight/volume,), molarity, molality, parts per million (ppm), or mole fraction. The concentration shows the amount of solute in a unit of the amount of solvent.
Volume of agua oxigenada are in a 400mL bottle of this solution: 12 ml
Further explanation
There are several concentration units in percentages that can be used.
Percent Volume (% V / V): total volume (ml) of solute in 100 ml of solution.
Can be formulated:
\tt \%volume=\dfrac{volume~solute}{volume~solution}\times 100\%%volume=
volume solution
volume solute
×100%
Given
A bottle of hydrogen peroxide also known as agua oxigenada is labeled 3%
(v/v) in a 400mL bottle
Required
Volume of agua oxigenada
Solution
3% v/v indicates that there are 3 ml of agua oxigenada in 100 ml of solution
So for 400 ml of solution, volume of agua oxigenada:
\begin{gathered}\tt =\dfrac{3}{100}\times 400\:ml\\\\=\boxed{\bold{12\:ml}}\end{gathered}
=
100
3
×400ml
=
12ml
