200 gm of an oelum sample (labelled as 109 % ) is mixed with 400 gm of another oleum sample (labelled as 118 % ). The labelling of the new sample formed will be :

An oleum sample contains 10 g SO_(3) and 15 g H_(2) SO_(4) Answer the following questions on the basis of above information : % labelling of oleum sample is .

Find the % labelling of 100 gm oleum sample if it contains 20 gm SO_(3)

Oleum is considered as a solution of SO_(3) in H_(2)SO_(4) , which is obtained by passing SO_(3) in solution of H_(2)SO_(4) When 100 g sample of oleum is diluted with desired mass of H_(2)O then the total mass of H_(2)SO_(4) obtained after dilution is known is known as % labelling in oleum. For example, a oleum bottle labelled as ' 019% H_(2)SO_(4) ' means the 109 g total mass of pure H_(2)SO_(4) will be formed when 100 g of oleum is diluted by 9 g of H_(2)O which combines with all the free SO_(3) present in oleum to form H_(2)SO_(4) as SO_(3)+H_(2)O to H_(2)SO_(4) What is the % of free SO_(3) in an oleum that is labelled as '104.5% H_(2)SO_(4)' ?

A sample of fuming sulpheric acid containing H_(2)SO_(4), SO_(3) and SO_(2) weighing 1.00g is found to require 23.47mL of 1.00 M alkali (NaOH) for neutralisation. A separate sample shows the presence of 1.50% SO_(2) . Find the percentage of "free" SO_(3),H_(2)SO_(4) and "combined" SO_(3) in the sample.
