    Given:

    mass of sodium acetate = 18.0 grams

    volume of acetic acid = 510 ml

    concentration of acetic acid = 0.160 M

    Solve for the ph of the buffer:

    pH = pKa + log [salt]/[acid]

    pKa of acetic acid = 4.76

    M of sodium acetate = 82g/mol

    pH = 4.76 + log [18g/82g/mol] / [0.160M * (510/1000) ]

    pH = 5.19
