do fast fast plz don't write incorrect answer

Answer 1

Answer:

Carbon

CO2=44

C=12

8.45 of CO2 contain C

=12×8.45/44=2.3mg

% of C=2.3×100/4.24=54.3%

Hydrogen

H2 O=18

H=1

3.46mg of H2O contain H

=0.384mg

% of H=0.384×100/4.24=9%

% of O=100-(9+54.3)=36.7%

C 54.3 12 54.3/12=4.52 4.52/2.29 =1.9 ~2

H 9 1 9/1=9 9/2.29=3.9~4

O 36.7 16 36.7/16=2.29 2.29/2.29=1

EMPIRICAL FORMULA:C2 H4 O

Mass of EMPIRICAL Formula =44

n=88/44=2

Molecular formula::C4 H8 O2
