To calculate the molar mass of glycerol (C3H8O3), we need to consider the atomic masses of each element in the compound.
Here’s the breakdown:
- Carbon (C): There are 3 carbon atoms. The atomic mass of carbon is approximately 12.01 g/mol. So, for carbon: 3 x 12.01 = 36.03 g/mol
- Hydrogen (H): There are 8 hydrogen atoms. The atomic mass of hydrogen is approximately 1.01 g/mol. So, for hydrogen: 8 x 1.01 = 8.08 g/mol
- Oxygen (O): There are 3 oxygen atoms. The atomic mass of oxygen is approximately 16.00 g/mol. So, for oxygen: 3 x 16.00 = 48.00 g/mol
Now, we can add these values together to get the molar mass of glycerol:
Molar Mass = 36.03 g/mol + 8.08 g/mol + 48.00 g/mol = 92.11 g/mol
Therefore, the molar mass of glycerol is 92.11 g/mol.
