In an unknown sample, the amount of ascorbic acid (C6H8O6) is determined using coulometry. Analysis of a 250.0 mg sample gives an endpoint with starch after reaction with electrogenerated iodine in 384 sec using a current of 30.0 mA. What is the % ascorbic acid, (C6H8O6), (FW= 176.12 g/mol) in the sample?
