-Calculate the amounts in grams of weak acid and conjugate base needed to make the buffer. Include your calculations to the end of the Buffer SOP Part II below. There is a section at the end of the template for?typing in your calculations. Show all your work and provide a brief summary of the steps you took to generate the calculation.Buffer:
pH = 5.0
concentration = 0.2M
volume = 500 mL
weak acid = acetic acid (MW 60.1)
conjugate base = sodium acetate (MW 82.0)
pKa = 4.75
