[" Percentage of free "SO_(3)" in "104.5%],[" oleum sample "]

What is the percentage of free SO_(3) in an oleum sample that is labelled as '104.5% H_(2)SO_(4) ?

The percentage labelling (mixture of H_(2)SO_(4) and SO_(3)) refers to the total mass of pure H_(2)SO_(4) . The total amount of H_(2)SO_(4) found after adding calculated amount of water to 100 g oleum is the percentage labelling of oleum. The higher the percentage lebeling of oleum higher is the amount of free SO_(3) in the oleum sample. The percent free SO_(3) is an oleum is 20%. Label the sample of oleum in terms of percent H_(2) SO_(4) .

The total amount of H_(2)SO_(4) found after adding calculated amount of water to 100 g oleum is the percentage labelling of oleum. The higher the percentage lebeling of oleum higher is the amount of free SO_(3) in the oleum sample. 100 g sample of '149%' oleum was taken and calculated amount of H_(2)O was added to make H_(2)SO_(4) . 500 mL solution of x MKOH solution is required to neutralize the solution. The value of x is.
