if the concentration of NO3- in the water is uniformly 5 microMolar, how many moles of N are there per square meter?

Question

DrBob222 · Answer

I answered this question yesterday, partially, on another post, and calculated mols N/cubic meter. Then I noted that I don't know how to change cubic meters to square meters. I don't know if the question is flawed or if I am missing something.

i forgot to include that there is 10^4 L of water. i have tried to work it out and came up with 5x10^-2mol N

DrBob222 · Answer

mols N/cubic meter is a volume term. Square meters is an area term. 10^4 L is a volume, also. If you want to show your calcns I may be able to know what is required.

5x10^-6mol N/L * 10^4 L 5x10^-2 mol N
