Re: Amount of solvent

Okay, So I have 0.002 mole of yttriumoxide that means I should have 0.012 mole of nitric acid, Please can you tell me how I can calculate the amount of nitric acid.

Amount of solvent

I have this balanced reaction:
Y2O3 + 6HNO3 = 2Y(NO3)3 + 3H2O
How I can determine the amount of HNO3 (solvent)?
Thanks

Re: calculating the concentration

you mean like for substance A:
c=0.008/0.04 = 0.2 M , and for substance B:
c=0.016/0.04= 0.4 M ???

Re: chemical reaction

I added Trisodium citrate and sodium hydroxide but as shape modifiers, since I am trying to prepare spherical yttrium hydroxide nanoparticles. In the end I got precipitate and I was characterized by XRD, it was what I want but I did not know the chemical reaction.
