I'm still getting off somehow. Should micrometers ^2 = meters^(-12)? I'm not sure how to convert 3.72E(-17) mol/micrometers^3 in terms of mol/meters^3. Units. This should be 3.72 mol/m^3. From here, make sure you use 32 g/mol for oxygen since it is O2. I get about 10^(-12) grams per second. I thought I was getting this at first, but the more I work on it, the more confused I get.
