CH3CH3CH2O2
C2H5OH
C4H10O2
C4H12O2
CH3CH3CH2OOH

Answer 1

1.elements: carbon. hydrogen. oxygen

2.percentage: 52.14. 13.13. 34.73

3.Number of :

moles, you 4.345. 13.13 2.171

divide the

% with mass

number.

4.mole ratio, : 2 6 1

you divide

with the

list number

of moles

throughout.

5.The formula C2H5OH

of the sample:

Step-by-step explanation:

Just follow the steps above are well explained ,thank

Answer 2

C4H12O2

Step-by-step explanation:

Molar mass of Carbon=12

Molar mass of Hydrogen =1

Molar mass of Oxygen = 16

C H O

52.14/12 13.13/1 34.73/16

4.345/2.17 13.13/2.17 2.17/2.17

2 6 1

C2H6O

(C2H6O)2

C4H12O2
