5. A bioengineer needs 750mL of an acetic acid sodium acetate buffer at pH4.50. Solid sodium acetate (CH3COONa) and liquid acetic acid (CH3COOH) solution are available in the lab. Acetic acid solution is 85.0%CH3COOH by mass and has a density of 1.07g/cm3. If the buffer is to be 0.375M in CH3COOH, how many grams of CH3COONa, and how many milliliters of 85.0% acetic acid solution are necessary in preparation? Assume that dissolution of solid CH3COONadoesnt change the total volume of buffer solution. (25 p.)
