Conversion from μM to mg for NO3- and PO4-

[takayan]

How can I convert μM to mg unit for the value below?
38 μM NO3−
0.18 μM PO4−

You'll just have to work backwards.

Note that to get the molecular mass you will need to add the mass of all atoms in the compound. So, for NO3, you'd add N and O three times essentially.

Why are you measuring these in Moles? Don't think there is any test equipment that will even do that for you--it is a mathematics exercise if you want to actually know the number of specific molecules in something.

Thanks for your help.
I am reading an article that uses Mol instead of ppm.
