I need help converting 90 ug/m^3 to ppm
I know there is some dimensional analysis involved, but I am just not sure where to start or how to do it in this particular conversion?
edit: here is the actual question: Did any of the measurements exceed the National Ambient Air Quality Standard for ozone for 1-hour exposure? For 8 hour exposure?
Here is what I have as my answer so far: According to the EPA website, the standard for 1-hour exposure of ozone is 0.12 ppm, and the standard for 8-hour exposure is 0.070 ppm.
here is the data table needed for the conversions:
