    The mass percent of oxygen in Barium perchlorate is is 38%.

    The molecular mass of Barium perchlorate (Ba (ClO4) 2) is 336.2282 g/mol.

    Percent composition of Oxygen will be = [ (Molecular mass of Oxygen X 8) / Molecular mass of Barium perchlorate] X 100%

    = [ (15.99 X 8) / 336.2282] X 100% = 38%
