2.2 Exercise 19

Avg difficulty 2.5

In the problems in this section, assume all gases are ideal.

If the rms speed of oxygen molecules inside a refrigerator of volume 22.0ft.322.0 \text{ft} .^{3} is 465 m/s, what is the partial pressure of the oxygen? There are 5.71 moles of oxygen in the refrigerator, and the molar mass of oxygen is 32.0 g/mol.
