A 130.0 −mL buffer solution is 0.105 M in NH3 and 0.135 M in
NH4Br. What mass of HCl can this buffer neutralize before the pH
falls below 9.00? If the same volume of the buffer were 0.250 M in
NH3 and 0.390 M in NH4Br, what mass of HCl could be handled before
the pH falls below 9.00? Need answer in grams. PS the answer is not
