Answer:
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:
Explanation:
Just follow the steps above are well explained ,thank
C4H12O2
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
put them in where the letters start with
