Surfing For How Many Molecules Of Air Are In A Room?

Charles asks…chemistry help!?hey i need help with these chemistry problems:

1. Mexico has set an air quality standard of 110 ppb for ozone, but frequently the ozone levels actually measured are much higher. The concentration of ozone in Mexico City has been measured at 441 ppb (0.441 ppm). Mexico City sits at an altitude of 7400 ft which means atmospheric pressure is only 0.67 atm. Calculate the partial pressure of ozone at 441 ppb if the atmopsheric pressure is 0.67 atm.

2. The
