i need help woth this!!
Part A K. From the value Ke = 1.2 x 10° for Ni(NH3).2+, calculate the concentration of NH3 required to just dissolve 0.024 mol of NiC 04 (K,p = 4 x 10-1) in 1.00 L of solution. (Hint: You can neglect the hydrolysis of C,0,2- because the solution will be quite basic.) Express your answer using two significant figures. Iyo AEO ?
