Commercial drain cleaners nowadays make use of different bleaching agents called oxyhalide compounds such as sodium hypochlorite and sodium chlorate. Starting with the same mass for each compound,
which of these has a greater % oxygen composition?

the formula of the compounds?
sodium hypochlorite = NaOCl
sodium chlorate = NaClO3
which of these has a greater % oxygen composition?
Just looking at the formulas, you can see that sodium chlorate has three times as much oxygen as sodium hypochlorite.
How many percent? [percent of what?]
NaOCl = 74.4422 g/mol
O = 15.99943 g/mol
(15.99943 g/mol) / (74.4422 g/mol) = 0.214924 = 21.4924% O in NaOCl
NaClO3 = 106.441 g/mol
O3 = 47.9982 g/mol
(47.9982 g/mol) / (106.441 g/mol) = 0.450937 = 45.0937% O in NaClO3
