Answer:
176.36g/mol
Explanation:
It was given that:
Mass of ascorbic acid=0.552 g
Volume of water=20.0 mL
Concentration of KOH=0.1103 M
Volume of KOH=28.42 mL. = 0.02842l
pH of solution at 10.0 mL= 3.72
At equivalence point, number of moles of acid is equal to the number of moles of base.
Number of moles of base= (KOH) x Volume
=0.1103 x 0.02842 L
=0.00313 moles.
Therefore number of miles of acid= 0.00313moles
No of moles= Mass/molar mass
Molar Mass= Mass of Acid/ No of moles of acid
= 0.552g/0.00312moles
= 176.36g/mol
