Question 3 - Lab 7

I am confused with the units in eq 6. First, I am thinking that dCO2/dt is the average slope from Q2. If so, the units are ppm/sec or mass/volume/sec, right? If that is the case then how do you get F (µmol m-2 s -1)?

F (µmol m-2 s -1) = (m-3 x m3)/m2 x µmol/?/sec

Thanks.

The constant in etn 6 pV/A has units of umol/m2 dCO2/dt is the rate of change in concentration (per second) Thus units for F = umol m^-2 s^-1
