A biochemist needs 750 mL of an acetic acid–sodiumacetate buffer with pH 4.50. Solid sodium acetate(CH3COONa) and glacial acetic acid (CH3COOH) areavailable. Glacial acetic acid is 99% CH3COOH by massand has a density of 1.05 g/mL. If the buffer is to be 0.15 Min CH3COOH, how many grams of CH3COONa and howmany milliliters of glacial acetic acid must be used?

100%

A biochemist needs 750 mL of an acetic acid–sodium
acetate buffer with pH 4.50. Solid sodium acetate
(CH₃COONa) and glacial acetic acid (CH₃COOH) are
available. Glacial acetic acid is 99% CH₃COOH by mass
and has a density of 1.05 g/mL. If the buffer is to be 0.15 M
in CH₃COOH, how many grams of CH₃COONa and how
many milliliters of glacial acetic acid must be used?
