c) Total volume of standard solution prepared (mL) was 100 ml
d. Ascorbic acid concentration in standard solution (mol/L):
Converting 100 ml= 0.1 L
C6H8O6= 176.12412 g/mole
= 176.12412 g
Find the mole of Ascorbic first:
= 0.05g * (1 mole / 176g)
= 2.83891* 10^-4 mole
Ascorbic acid concentration :
=2.83891*10^-4mole / 0.1 L
=0.0028 mole/L
2.a.Volume of Iodine (I2) added
=50 ml - 12.35 ml
= 37.65 ml
