As part of your summer vacation, you are planning to revolutionize the field extreme sports. Your goal is to skydive out of a plane and land on the summit of Mt. Everest followed by a quick decent via snowboard to the base camp - all without supplemental oxygen. Because of your excellent health and training, your doctor says you can probably stay conscious for about 30 seconds at 35,000 feet (10,668 meters) which is enough time to land on Mt. Everest (29,029 ft. (8,848 meters). Compare the concentrations of oxygen (in moles m ^-3 and molecules cm ^-3 ) when you jump out of the plane, when you land on Mt. Everest, and when you get back to sea level. Clearly indicate the pressures and temperatures you use at each altitude. You can read them from class slides or get more accurate values from the web.

2. a) molecules cm ^-3  
3. b) mg m ^-3  
4. How much light is transmitted by a 10 M column of ozone at 30km the following wavelengths  
5. a) 250 nm and 
6. b) 300 nm. Assume the pressure is 10mbar, T=240K, O3 is 6 ppm.
