Formula of ethanol is c2h5oh. What will be it's molecular mass
Answers
Answer:
MOLECULAR MASS:
- Go step wise.
C2H5OH :
========
- Molecular weight of carbon is 12
- Since two carbons are there 2 × 12 = 24
- Molecular weight of hydrogen is 1
- Since five hydrogen are there 5 × 1 = 5
- Molecular weight of O and H is 16 + 1 = 17
- Add them all
The final answer is 24 + 5 + 17 = 46

Answer:
46u
Explanation:
in question user asking about the molecular formula of ethanol and also we find the molecular mass of ethanol .
now,
the molecular formula of Ethanol is C2H5OH.
and also,
the IUPAC name of C2H5OH is ethanol.
again we find the molecular mass of the ethanol .
when we find the molecular mass of the compounds.
we are adding the atomic weight of molecule which are constituents in compounds.
like , here 3 constituents
carbon , hydrogen , oxygen
in the ethanol compound number of carbon molecule is equal to 2.and the atomic mass of carbon equal to 12 .
since , 12 × 2 = 24
in the ethanol compound the total number of hydrogen molecule equal to 6
atmoic weight of hydrogen equal to 1.
since, 6×1 = 6
in the ethanol compound the number of oxygen molecule equal to 1.atmoic weight of oxygen equal to 16 .
since 16 × 1 = 16
adding all molecule weight of the compound .
24 + 6 + 16
30 + 16
46u.
therefore the Molecular mass if ethanol compound is equal to 46.
