    Hi everyone,

    Does anyone know how to convert O2 consumption rate that has units of mol/l/s into
    something that has units of s^-1.
    I want to convert the units because I need to use 's^-1' for my mathematical model. I searched everywhere but couldn't find an answer.

    Thanks in advance,

    well to get something in units of mols  \, l^{-1} \, s^{-1} into something with the units s^{-1} you're going to have to multiply it by something with units l \,  mols^{-1} or divide by something with the units mols \, l^{-1}

     mols \, l^{-1} sounds like the more obvious thing

    you mean multiply it by something with units mol^-1 l ? yes I thought about that... but what exactly is this quantity?

    well dividing by something with mols l-1 makes more sense as i'm sure you can work out how many moles in a litre

    Um. I could be wrong, but I'm fairly sure that mol/l/s is

    'Moles Per Litre Per Second'

    Which is m l^{-1} s^{-1}

    thanks for your reply but I'm not a chemist and wouldn't know how to but let me have a go:

    say O2 consumption rate was 7x10^-5 mol/l/s

    1mole O2 = 32 g

    then what?

    and what do both units mean in terms of O2 consumption?

    Oh, you meant just s^{-1} units, sorry

    Um, I dont know... Find the litres per mole and multiply by that? That'd be

     l m^{-1} \times m  l^{-1} s^{-1} = s^{-1}

    so how do I find the litres per mole? thats my question

    Google: 26.2 L/mol for oxygen.
