Hi,

I'm trying to calculate the flow rate for O2 in a DMFC 5cm2.

I already know that the number of required moles is 8.64*10^-6mol/s (from stoichiometry: CH3OH + 3/2O2 -> CO2+ H2O). But I'm not sure about how to calculate the flow in ml/min. Should I use the gas law: PV=nRT? Or can I simply use the molecular weight and the density of O2?

Thanks a lot
Francesca
