Design a buffer that has a pH of 8.62 using one of the weak base/conjugate acid systems shown below.

Weak Base	K_b	Conjugate Acid	K_a	pK_a
CH₃NH₂	4.2×10^-4	CH₃NH₃⁺	2.4×10^-11	10.62
C₆H₁₅O₃N	5.9×10^-7	C₆H₁₅O₃NH⁺	1.7×10^-8	7.77
C₅H₅N	1.5×10^-9	C₅H₅NH⁺	6.7×10^-6	5.17

How many grams of the bromide salt of the conjugate acid must be combined with how many grams of the weak base, to produce 1.00 L of a buffer that is 1.00 M in the weak base?

grams bromide salt of conjugate acid =

grams weak base =
