What is Molecular Mass?

Molecular mass, also known as molecular weight, is the sum of the atomic masses of all the atoms in a molecule. It is typically expressed in atomic mass units (amu) or daltons (Da). For compounds like ethane (C2H6), the molecular mass is calculated by adding the atomic masses of carbon © and hydrogen (H) atoms present in the molecule.

Calculating the Molecular Mass of C2H6

To calculate the molecular mass of C2H6, we need to know the atomic masses of carbon and hydrogen. The atomic mass of carbon is approximately 12.01 amu, and the atomic mass of hydrogen is approximately 1.008 amu.

Ethane (C2H6) has two carbon atoms and six hydrogen atoms. The calculation is as follows:

Molecular mass of C2H6 = (2 × atomic mass of C) + (6 × atomic mass of H)

Molecular mass of C2H6 = (2 × 12.01 amu) + (6 × 1.008 amu)

Molecular mass of C2H6 = 24.02 amu + 6.048 amu

Molecular mass of C2H6 = 30.068 amu

Therefore, the molecular mass of C2H6 is approximately 30.068 amu.

Importance of Molecular Mass in Chemistry

The molecular mass of a compound is essential for several reasons:

Stoichiometry: It helps in determining the amounts of reactants and products in chemical reactions.
