Calculate the amount of Tris(hydroxlmethyl)aminomethane(Tris) necessary to make 100mL of a 0.100 M Tris buffer that is equimolar in Tris-base (MW=121.1 g/mol) and Tris-HCL (MW= 157.6g/mol)

Thanks for answering the first one :) Here is another Calculate the amount of sodium acetate and acetic acid necessary to make 100mL of a 0.500 M acetate buffer that is pH 5.2. I believe I have the answer but I want to make sure I did the work correctly.

I have the pka from previous problems 4.75
