What is the mass??????

AIEEE 2015 Answers › Physical Chemistry questions › What is the mass??????

A 0.127g of unsaturated oil was treated with 25mL of 0.1M ICl solution.The unreacted ICl was then treated with excess of KI.Liberatd iodine reqd.40mL 0.1M hypo solution.Determine mass of I₂ that would have been reqd with 100g oil if I₂ were used in place of ICl?

meq of hypo=meq of I2=40*0.1=4
mmol of I2=4/2=2

mmol of ICl reacted with KI=2

mmol if ICl taken=2.5
mmol of ICl reacted with oil=2.5-2=0.5

mmol of I2 that woul react with .127 gram of oil=0.5
mmol of I2 that wud react with 100 g of oil = (100/0.127)*0.5
Wt.=(100/0.127)*(0.5/1000)*254

=100 g
