Question

the 2 answers for both questions are right are right i just need the steps, i gave you 2 questions so you can double check your that the steps are right

Propionic acid is provided (pka = 2.0) to make a 0.1 M buffer at pH = 2.0. What is the ratio of
proprionate:proprionic acid (round to the nearest whole number): 1_ What volume of a 1M
solution of proprionic acid is required to make 1 L of buffer (answer in mL, rounded to the
nearest whole number):
