if 53.0mL of 0.150M of HCl is needed to neutralize all the NH3 from a 2.28g sample of organic material. what is the mass percent of notrogen in the sample?

  • chemistry -

    NH3 HCl ==> NH4Cl
    mols HCl = M x L = ?
    mols NH3 must be the same as mols HCl.
    mols N (not N2) = same as mols NH3.
    g N = mols N x atomic mass N = ?
    %N = (grams N/mass sample)*100 = ?
