Carbon = 92.24%
Hydrogen = 7.76%

Explanation:

Begin by calculating the gram formula mass of the molecule #C_6H_6#

Carbon 6 atoms
Hydrogen 6 atoms

#C = 6*12.01 = 72.06#
#H = 6*1.01 = 6.06#

#C_6H_6 = 72.06 +6.06 = 78.12#

Now divide the individual element mass values by the molecular mass value.

#C = 72.06/78.12 = 92.24%#
#H = 6.06/78.12 = 7.76%#
