Understanding Molar Mass

The molar mass of a substance is the mass of one mole of that substance. It is typically expressed in grams per mole (g/mol). For glucose, which has the chemical formula C6H12O6, the molar mass is calculated by summing the atomic masses of all the atoms in the molecule.

Calculating the Molar Mass of Glucose

To calculate the molar mass of glucose, we need to know the atomic masses of carbon ©, hydrogen (H), and oxygen (O). The atomic masses are approximately:

Carbon ©: 12.01 g/mol
Hydrogen (H): 1.008 g/mol
Oxygen (O): 16.00 g/mol

The molecular formula for glucose is C6H12O6. Therefore, the calculation is as follows:

Molar mass of glucose = (6 × 12.01 g/mol) + (12 × 1.008 g/mol) + (6 × 16.00 g/mol)

Molar mass of glucose = (72.06 g/mol) + (12.096 g/mol) + (96.00 g/mol)

Molar mass of glucose = 180.156 g/mol

Thus, the molar mass of glucose is approximately 180.156 g/mol.
