Chemistry

1) How many grams of dry NH4Cl need to be added to 2.40 L ofa 0.800 M solution of ammonia, NH3, to prepare a buffer solutionthat has a pH of 8.82? Kb for ammonia is 1.8 x 10^-5.

2) A beaker with 150 mL of an acetic acid buffer with apH of 5.000 is sitting on a benchtop. The total molarity of acidand conjugate base in this buffer is 0.100 M. A student adds 6.80mL of a 0.490 M HCl solution to the beaker. How much will the pHchange? The pKa of acetic acid is 4.740.
