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