A 130.0 −mL buffer solution is 0.100 M in NH3 and 0.130 M in NH4Br.

Part A :

What mass of HCl can this buffer neutralize before the pH falls below 9.00?

Part B:

If the same volume of the buffer were 0.255 M in NH3  and 0.400 M in NH4Br, what mass of HCl could be handled before the pH falls below 9.00?
