QUESTION:

Problem 3PE

(a) What is the mass of a deep breath of air having a volume of 2.00 L? (b) Discuss the effect taking such a breath has on your body’s volume and density.

ANSWER:

Solution 3PE

We are given the volume of air. We are required to calculate the mass of this volume of air. We are also required to describe the effect of deep breath on our body’s volume and density.

Part a

Step 1 of 2

The volume of the given amount of air is 2.00 L.

The density of dry air is 1.29 g/L.

Therefore, the mass of 2.00 L of air g/L X 2.00 L

                                                          g

Therefore, 2.00 L of air has a mass of 2.58 g.
