# units conversion watch

1. 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.

2. well to get something in units of into something with the units you're going to have to multiply it by something with units or divide by something with the units

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

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?

yes, thats just another way of writing it

Oh, you meant just units, sorry

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

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