Chapter 8: Q. 8.62 (page 259)

Using the answer from problem $8.61$ , how many grams of nitrogen are in Whitney's lungs at STP if the air contains $78 %$ nitrogen?

Short Answer

Expert verified

Whitney's lungs are in $2.75 g o f N_{2}$ .

Step by step solution

Given Information

We need to find how many grams of nitrogen are in Whitney's lungs.

Simplify

Now,

$2.8 L$ is $100 %$ of air and it is equal to the lung capacity.

so,

$\frac{2.8 L}{100 %}$

calculate $78 %$ of $2.8 L$ :

$78 % \times \frac{2.8 L}{100 %} = 2.2 L$

The volume of the pure nitrogen in the air mixture of gases is $2.2 L$ .

Conversion factor:

$\frac{1 m o l o f N_{2}}{22.4 L o f N_{2}}$

calculating mole:

$\frac{1 m o l o f N_{2}}{22.4 L o f N_{2}} \times 2.2 L o f N_{2} = 0.098 m o l o f N_{2}$

We can present this with the conversion factor below:

$\frac{1 m o l o f N_{2}}{22.4 L o f N_{2}}$

Calculating how many grams of nitrogen :

$\frac{1 m o l o f N_{2}}{22.4 L o f N_{2}} \times 0.098 m o l o f N_{2} = 2.75 g o f N_{2}$
