What I need to figure out:
We did a gravimetric analysis lab and I have masses for the DMG-Ni complexes that we recovered but I need to find the percent nickel in each sample.
Relevant Equations: I believe you take the mass of the DMG-Ni complex sample and multiply that by the mass ratio of Ni2+ over the FW of DMG. Then divide the result by the mass of the sample and multiply by 100%.
I did what I layed out above but I get the same percentage Ni2+ for each sample which doesn't make sense so I must have gone wrong. Any help would be great![/B]
