Question

21.46 mL of Iodine I2 was standards with 0.1004 g sample of ascorbic acid. At the blue starch end point, what is the molarity of the iodine I2 solution?

Answer 1

Do you know the equation. You will need that.
moles ascorbic acid = grams/molar mass
Use the equation to convert moles ascorbic acid to moles I2.
M I2 = moles I2/L

Answer 2

so par say i should convert .1004 g ascorbic acid to mole/L.... if so then, is the 12 mole/L the conversion factor here?

Answer 3

The conversion factor comes from the equation of ascorbic acid + I2 ==> ??
