Please fill out the last 2 boxes the theortical  and % error

Answer 1

NaHCO3 Calculated Ab= 1.9 xlo to Theoretrial ko = 2.38x108 al error = Theoretical - calculated loo Theoretical 2.38x108 - 1.axlo to xloo 2:38 X 10 8 = 99.2011 NHuci Calculated Ka= 1.25x109 Theoretical Ra = 5.6x10-10 l error 5./5i6x10 to 1,25x169 5.6810 to =-123.4. - sign indicates calculated value is higher than theoretical one
