Question

Formula of ethanol is c2h5oh. What will be it's molecular mass

Answer 1

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 2

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.
