Assume air contains 21% oxygen and 79% nitrogen.

If air is compressed to 5.5atm, what is the partial pressure of the oxygen?

2

A gas in a container is at is compressed to a volume of . What is the new pressure of the container?

3

A $\small 4.5L$ container of gas has a pressure of $\small 3.0atm$ at a temperature of $\small 100^oC$ . The container is expanded to $\small 6L$ , and the temperature is increased to $\small 200^oC$ .

What is the final pressure of the container?
