Chapter 9: Q. 9.95 (page 318)

How many milliliters of a $12 % (v / v)$ propyl alcohol solution would you need to obtain $4.5 m L$ of propyl alcohol? $(9.4)$

Short Answer

Expert verified

As an outcome, $38 m L$ of $12 (v / v)$ liquid is forced to hold $4.5 m L$ of solute.

Step by step solution

Given information

The volume of solute absorbed in a 100 mL af mixture is the volume percent v/v. The formula for calculating volume percent is:

$v o l u m e p e r c e n t (v / v) = \frac{v o l u m e s o l u t e}{v o l u m e o f s o l u t i o n} \times 100$

$12 % (v / v)$ propyl alcohal indicates $12 m L$ propyl alcohal in a solution of $100 m L$ .

The volume percent converts to a conversion factor of $\frac{12 m L p r o p y l a l c o h o l}{100 m L s o l u t i o n}$ .

Explanation.

Find the volume of a $12 % (v / v)$ solution having $4.5 m L$ of propyl alcohol.

The volume of the solution is,

role="math" $= 4.5 mL propylatcohol \times \frac{100 mL solution}{12 mLpropytatcohol}$

$= 38 m L s o l u t i o n .$

As a result, $38 m L$ of $12 (v / v)$ solution is required to hold $4.5 m L$ of solute.
