What is the Molar Mass of Glucose?
The molar mass of glucose is a measure of the mass of one mole of glucose molecules. It is calculated by summing the atomic masses of all the atoms present in a single glucose molecule. Glucose is a hexose sugar, composed of six carbon atoms, twelve hydrogen atoms, and six oxygen atoms. The molecular formula for glucose is C6H12O6. To calculate the molar mass, we need to multiply the atomic mass of each element by the number of atoms present and then sum the results.The atomic masses of carbon, hydrogen, and oxygen are 12.01 g/mol, 1.01 g/mol, and 16.00 g/mol, respectively. Using these values, we can calculate the molar mass of glucose as follows:
| Element | Atomic Mass (g/mol) | Number of Atoms | Contribution to Molar Mass |
|---|---|---|---|
| Carbon | 12.01 | 6 | 72.06 |
| Hydrogen | 1.01 | 12 | 12.12 |
| Oxygen | 16.00 | 6 | 96.00 |
| 180.18 |
Therefore, the molar mass of glucose is 180.18 g/mol.
