Answer:
The Answer is 88%
Explanation:
The balanced ionic equation of the reaction
Looking at the above reactions
The original number of moles of = 3 × number of moles of
= 3 × volume × concentration of
Note: The formula for number of moles is volume × concentration
mol
The number of moles of left after its reaction with ascorbic acid
= x moles of
= x volume x concentration of
Note: The division by 1000 is to convert mill liter to liter
Moles of ascorbic acid = moles of reacted
Hence
Mass of ascorbic acid = moles of ascorbic acid × molar mass of ascorbic acid
Weight% of ascorbic acid = mass of ascorbic acid/mass of sample x 100%
= 70.55/80 × 100%
= 88.1%
