Question

Calculate the percentage of mass of carbon in ethanoic acid

Answer 1

Answer:

The percent composition of carbon in acetic acid is

40.002%

Explanation:

Acetic acid:

CH

3

COOH

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

(2×12.011 g/mol) in one mole of acetic acid and multiply by

100 .

2×12.011gmol 60.052gmol×100= 40.002%
