Oleum, also known as fuming sulfuric acid or pyrosulfuric acid, is a solution of sulfur trioxide (SO3) in concentrated sulfuric acid (H2SO4).
Oleum is another name for very pure sulfuric acid (above 98%). Oleum is not a part of sulfuric acid.
Dissolve excess Sulfur trioxide in concentrated Sulfuric acid
Yes, BUT... Liquid SO3 is HIGHLY reactive and not readily available. Pure SO3 reacts readily (and violently) with water or sulfuric acid. To manufacture sulfuric acid, dilute gaseous SO3 is absorbed in sulfuric acid to increase the concentration of the acid. 100% sulfuric acid can still absorb more SO3. When extra SO3 is dissolved in 100% H2SO4 (sulfuric acid) the solution is called oleum or fuming sulfuric acid. In general, oleum is used when free SO3 is required.
The traditional Latin name for fuming sulfuric acid is Oleum. It comes from the Latin word for oil (oleum). It is also called Nordhausen acid.
By dissolving Sulfur trioxide in concentrated Sulfuric acid
Oleum is typically produced by dissolving sulfur trioxide (SO3) in concentrated sulfuric acid (H2SO4).
Oleum is more stronger acid than Sulfuric acid
The traditional name for fuming sulfuric acid is Oleum. Oleum is used for in water based aerosol coatings. Rust-Oleum has the fuming sulfuric acid in its name and hold many patents on its usage.

Oleum or fuming sulfuric acid refers to a solution of various compositions of sulfur trioxide (SO3) in sulfuric acid (H2SO4), which can also be described by the formula H2SO4.xSO3 where x is defined as the molar free sulfur trioxide content.As being a mixture it does not have a chemical structural formula.
Dodycyle benzene is reacted with oleum or sulfuric acid in slow addition and strong agittation manner
No. 50% Sulfuric acid is 18.4 Normal. 50N (Normal) sulfuric acid is, umm, 136% (not possible).
The answer depends on the dilution factor and if the sulfuric acid was 100% to start.
