Your current Vmax (4x10-3 A/S) from the Michaelis-Menten plot has the units of A/s and was determined using 0.1 mg of ADH in a total volume of 1.25 mL. Use the Beer-Lambert equation followed by simple conversion to express your estimated Vmax in (mol )/s per 1 mg ADH. The molar absorptivity of NADH at 340 nm is 6220 L/(mol*cm).
