Question
Determine the Osmolarity of
M= mol / L : M = 0.029 mol Li3N / 0.5= 0.058 M Li3N
When exactly 0.500 mL of 0.0287 M Cu(N03)2 was added the signal increased to 37.9 units. Calculate the molar concentration of Cu^2. assuming that the signal was directly proportional to the analyte concentration.
