The molar mass of ethylene glycol (C2H6O2) is approximately 62.07 g/mol.
To calculate the molar mass, we consider the molecular formula of ethylene glycol. It comprises 2 carbon (C) atoms, 6 hydrogen (H) atoms, and 2 oxygen (O) atoms. Here’s how the calculation is done:
- Carbon: 2 atoms × 12.01 g/mol = 24.02 g/mol
- Hydrogen: 6 atoms × 1.008 g/mol = 6.048 g/mol
- Oxygen: 2 atoms × 16.00 g/mol = 32.00 g/mol
Adding these together gives:
24.02 g/mol + 6.048 g/mol + 32.00 g/mol = 62.07 g/mol
This value is important in various applications, especially in chemistry and industry, where ethylene glycol is used as an antifreeze, coolant, and in the production of polyesters.
