#"11.02 mol C"_2"H"_6"O"#

Explanation:

Calculate the molar mass of #"C"_2"H"_6"O"#.

#2xx"molar mass of C"=2xx12.01 "g/mol"=24.02"g/mol"#
#6xx"molar mass of H"=6xx1.01"g/mol"=6.06"g/mol"#
#1xx"molar mass of O"=1xx16.00"g/mol"=16.00"g/mol"#

The sum of the molar masses of each atom is #46.08"g/mol"#.

#508color(red)(cancel(color(black)("g")))xx(1"mol")/(46.08color(red)(cancel(color(black)("g"))))="11.02 mol C"_2"H"_6"O"#
