hi all,
I have recently received results from an analysis of some sea water i had collected. The results were for the TOTAL dissolved nitrogen in the samples, ( organic and inorganic ) and were given in micromolar concentrations, um. For example sample1a=738uM=738x10-6M
how do i go about converting these into mass/volume, ie mg/L?
edit: just checked the raw data, and the column is labelled as follows:
TDN con (µM)
713.4
723.6
etc
so i take it thats a concentration as in µMol/dm3. Would I just need to multiply by 14 ( Mr of N ) to convert into grams?
