a 3.250 g sample of petroleum fraction was ignites in a Parr bomb under a 20 atm pressure of O2. all the sulfur was converted into SO3 and upon addition of water H2SO4 was formed. The SO4 was completely precipitated by addition of BaCl2, abnd precipitate of SaSO4 wt 253 mg. calculate %w/w sulfur in petroleum fraction
