Question

calculate the molecular masses of the following C2H5-OH​

Answer 1

Answer:

the molecular masses of C2H5-OH is 46 u

Answer 2

Answer:

Molar mass of C2H5OH = 46g/mol

Mass of One molecule of C2H5OH = 46amu

Explanation:

Atomic mass of C = 12amu

Atomic Mass of H = 1amu

Atomic mass of O = 16 amu

Molecular mass of C2H5OH = 12×2 + 5 × 1 + 16 + 1

                                               = 24 + 5 + 16 + 1

                                               = 29 + 17 = 46amu

Molar mass of C2H5OH = 46g/mol
