Domain Archaea
Like bacteria,Organisms in domain Archaea are prokaryotic and unicellular. Superficially, they look a lot like bacteria, and many biologists confused them as bacteria until a few decades ago.
Well the picture could help :)
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%
