I have dissolved oxygen data that is in units of µmol/liter.
I need to convert it to mmol/kilogram.
I have been told by someone who knows more about chemistry than I do (but only a little bit more) that I need to know the mass of my sample as well (which I don't know).
So only knowing my original DO data (in µmol/L) and the density of SW (assume 1.027 g/cm³), how does one convert the data to mmol/kg?
