#"SO"_4#

Molar mass of #"S"# is #"32 g/mol"#

Moles of 96 g sulfur is

#"96 g"/"32 g/mol" = color(red)"3 mol"#

Molar mass of #"O"# is #"16 g/mol"#

Moles of 192 g oxygen is

#"192 g"/"16 g/mol" = color(red)"12 mol"#

# #

So, an oxide of sulfur contains, #"3 mol S"# and #"12 mol O"#

Molecular formula #"= S"_3"O"_12#

Emperical fromula #"= SO"_4#
