#6. A 130.0 mL buffer solution is 0.110 molL−1 in NH3 and 0.125 molL−1 in NH4Br.

A) What mass of HCl will this buffer neutralize before the pH falls below 9.00? (Kb(NH3)=1.76×10−5)

B)If the same volume of the buffer were 0.270 molL−1 in NH3 and 0.390 molL−1 in NH4Br, what mass of HCl could be handled before the pH fell below 9.00?
