A 130.0 −mL buffer solution is 0.100 M in NH3 and 0.135 M in NH4Br.

Part A What mass of HCl can this buffer neutralize before the pH falls below 9.00? Express the mass in grams to three significant figures.

Part B If the same volume of the buffer were 0.270 M in NH3 and 0.390 M in NH4Br, what mass of HCl could be handled before the pH falls below 9.00?
