Calculate the mass of a mole of glucose, C6H12O6, in grams.
Would I just find the GFM, which comes out to 180.0g?
Yes.
Yes, to calculate the mass of a mole of glucose, you need to determine its molar mass or molecular weight.
First, you have to find the molar mass of each element in glucose (C6H12O6).
The atomic mass of carbon (C) is 12.01 g/mol, hydrogen (H) is 1.01 g/mol, and oxygen (O) is 16.00 g/mol.
Next, you multiply the molar mass of each element by the number of atoms present in one molecule of glucose:
- Carbon (C) has 6 atoms, so 12.01 g/mol x 6 = 72.06 g/mol
- Hydrogen (H) has 12 atoms, so 1.01 g/mol x 12 = 12.12 g/mol
- Oxygen (O) has 6 atoms, so 16.00 g/mol x 6 = 96.00 g/mol
Finally, you add up the individual masses of each element to find the molar mass of glucose:
72.06 g/mol (C) + 12.12 g/mol (H) + 96.00 g/mol (O) = 180.18 g/mol
Therefore, the molar mass of glucose is approximately 180.18 grams per mole (g/mol).
