Question

calculate the molecular mass of C2H5OH

Answer 1

Answer:

46 u

Explanation:

molecular mass of C2H5OH = Mass of C * 2 + mass of H * 6 + mass of O * 1

                                               = 12*2  + 1*6 + 16*1

                                               = 24 + 6 + 16

                                               = 46 u or amu

Answer 2

C₂H₅OH is Ethyl alcohol.It can be abbreviated as EtOH

Explanation:

Ethyl alcohol is also known as Ethanol or grain alcohol

• It is clear, colourless liquid which is volatile and inflammable liquid
• Its  taste is pungent
• it has a characteristics wine like odour and pungent smell.
• It is mainly used for alcoholic beverages.
• Molecular mass of Ethyl alcohol is determined as

Mol.mass=(2×Carbon)+(5×Hydrogen)+(Oxygen)+(Hydrogen)

=(2×12u)+(6×1u)+(1×16u)

=46u

The molecular mass of Ethyl Alcohol is 46u.
