Calculate the volume of acetic acid (CH³CO₂H) and the mass of sodium acetate (CH₂CO₂Na) needed in order to prepare 1.0 L of a 200 millimoles acetate buffer at pH 4.5. The original concentration of acetic acid is coming from a pure acetic acid (called "glacial") is a liquid at room temperature, with a density of 1.049 g/mL and a formula weight of 60.05 g/mol. Sodium acetate is a solid, with a formula weight of 82.03 g/mol.
