What is the Molar Mass of C2H6?

The molar mass of C₂H₆ (ethane) is calculated by adding the atomic masses of all the atoms in the molecule. Here’s how it’s done:

• Carbon (C) has an atomic mass of approximately 12.01 g/mol.
• Hydrogen (H) has an atomic mass of approximately 1.01 g/mol.

Since there are 2 carbon atoms and 6 hydrogen atoms in C₂H₆, the molar mass is calculated as follows:

Molar Mass = (2 × 12.01 g/mol) + (6 × 1.01 g/mol)

Molar Mass = 24.02 g/mol + 6.06 g/mol

Molar Mass = 30.08 g/mol

Therefore, the molar mass of C₂H₆ is 30.08 g/mol.
