Chapter 9: Q. 9.62 (page 309)

A doctor orders $100 m L o f 2.0 % (m / v)$ ibuprofen. If you have $8.0 % (m / v)$ ibuprofen on hand, how many milliliters do you need?

Short Answer

Expert verified

The volume of Ibuprofen is $25 m L$ is need when you have $8.0 % (m / v)$ ibuprofen.

Step by step solution

Given Information.

The following are the given information:

Mass per volume of ibuprofen is $2.0 % (m / v)$

To find the milliliters of Ibuprofen.

Find the Mass per Volume percent.

Using the following, find the mass per volume percent,

$Mass percent (m / v) = \frac{Solute mass}{Solution volume} \times 100 %$

Mass per volume percent of Ibuprofen is $2.0 % (m / v)$

Find the mass of Ibuprofen.

Volume of the solution is $100 m L$

$Solute mass = \frac{Mass percent (m / v) \times Solution volume}{100 %} = \frac{2.0 % \times 100 mL}{100 %} = 2.0 g$

We know that,

Mass per volume of the solution is $8.0 % (m / v)$

Mass of Ibuprofen is $2 g$

Find the volume of Ibuprofen.

$Solution volume = \frac{Solute mass}{Mass percent (m / v)} \times 100 % = \frac{2.0 g}{8.0 %} \times 100 % = 25 m L$

Therefore, the volume of Ibuprofen is $25 m L$
