Chapter 9: Q. 9.35 (page 305)

A mouthwash contains $22.5 % (v / v)$ alcohol. If the bottle of mouthwash contains $335 m L$ , what is the volume, in milliliters, of alcohol?

Short Answer

Expert verified

The volume of alcohol is $79 .9 mlofalcohol$ if the mouthwash contains $335 m L$

Step by step solution

Given Information.

The following are the given information to find the milliliters:

Mouthwash contains $22.5 % (v / v)$ alcohol.

If mouthwash contains $335 m L$ , find the volume in milliliters.

Explanation.

A conversion factor is a one-to-one ratio. Multiplying a quantity by a conversion factor keeps changing the units of measurement but does not change the original amount.

Equalities/conversion factor represents the milliliter of solute in $100 m L$ of solution.

$22.5 % (v / v)$ written as:

localid="1653466843727" $100 ml solution = 22.5 ml alcohol$

localid="1653466857271" $\frac{22.5 ml alcohol}{100 ml solution} and \frac{100 ml solution}{22.5 ml alcohol}$

The volume of the solution using conventional factors is,

localid="1653466871340" $= 355 ml sotuion \times \frac{22.5 ml alcohol}{100 ml sotulion} = 79.9 ml of alcohol$
