Is F2 bond is stronger than Br2 ?

Yes F₂ bond is stronger than Br₂.we know that bond strength of bond depend inversely proportional bond length, hence atomic size of fluorine is smaller than bromine so that F-F bond is smaller than Br-Br bond.

How to calculate % free SO3 in given Oleum sample ?

CALCULATIONS OF FREE SO₃ IN (X%) OLEUM SAMPLE :
Given - X %  labelled 100 gm Oleum,it means  (X-100) gm water required to destroyed all free SO₃present in 100 gm Oleum.
                                               W_H2O= (X-100) gm

BY STOICHIOMETRIC CALCULATION:

Weight of SO₃ = nSO3 X Molecular wt SO₃

Weight of H₂SO₄ = nH₂SO₄ X Molecular wt of H₂SO₄

 

thus % (Free) SO₃ present in 100 gm 109% labelled Oleum Sample is

What is the maximum % labelling of Oleum sample ?

For maximum possible labbelling amount of SO₃ is 100 gm, It means 100 gm Oleum sample contains 100 gm SO₃ only and zero( 0 )gm H₂SO₄ ,hence maximum labbelling possible is 122.5 %.
