Understanding Molar Mass

The molar mass of a substance is the mass of one mole of that substance. It is expressed in grams per mole (g/mol). For sucrose, the molar mass is determined by the sum of the atomic masses of all the atoms in its molecular formula, which is C₁₂H₂₂O₁₁.

Calculating the Molar Mass of Sucrose

To calculate the molar mass sucrose, we need to sum the atomic masses of all the atoms in its molecular formula. The atomic masses of carbon ©, hydrogen (H), and oxygen (O) are approximately 12.01 g/mol, 1.008 g/mol, and 16.00 g/mol, respectively.

Here is the step-by-step calculation:

Carbon (C): 12 atoms × 12.01 g/mol = 144.12 g/mol
Hydrogen (H): 22 atoms × 1.008 g/mol = 22.176 g/mol
Oxygen (O): 11 atoms × 16.00 g/mol = 176.00 g/mol

Adding these values together, we get:

144.12 g/mol (C) + 22.176 g/mol (H) + 176.00 g/mol (O) = 342.296 g/mol

Therefore, the molar mass sucrose is approximately 342.296 g/mol.
