The percent composition of carbon in acetic acid is #40.002%#.

Explanation:

To determine the percent composition of carbon in acetic acid, divide the molar mass of acetic acid #("60.052 g/mol")# by the mass of carbon #("2"xx"12.011 g/mol")# in one mole of acetic acid and multiply by #100#.

#(2xx12.011color(red)cancel(color(black)("g"))/color(red)cancel(color(black)("mol")))/(60.052color(red)cancel(color(black)("g"))/(color(red)cancel(color(black)("mol"))))xx100="40.002%"#
