You have titrated a standard solution of ascorbic acid that has a concentration of 20mg/1 mL. 1 mL of the solution required 6.5 mL of the titrant to change the color of the solution. You have a 1.0 mL sample of unknown concentration that requires 8.0 mL of titrant to change the color of the solution. How many mg of ascorbic acid are in your unknown sample
