calculate the number of DU assuming that the entire atmospheric O3 column is at a uniform concentration of 3*10^12 molecules/cm^3 between 15 km and 30 km and zero elsewhere.(adsbygoogle = window.adsbygoogle || []).push({});

I have no idea how to solve it. I don't know how to convert the 3*10^12 molecules/cm^3 to units of molecules/cm^2 that I can calculate by dividing in 2.69*10^16 molecules/cm^2 and give the DU.

Is anyone know how to solve this?

thank you,

Dorin
