The molar mass of CH2O, which is also known as formaldehyde, can be calculated by adding up the atomic masses of its constituent atoms: carbon (C), hydrogen (H), and oxygen (O).
In the molecular formula CH2O, there is 1 carbon atom, 2 hydrogen atoms, and 1 oxygen atom. Here are the atomic masses of each element:
- Carbon (C): approximately 12.01 g/mol
- Hydrogen (H): approximately 1.01 g/mol
- Oxygen (O): approximately 16.00 g/mol
Now, we can calculate the molar mass:
- Molar mass of C: 1 x 12.01 g/mol = 12.01 g/mol
- Molar mass of H: 2 x 1.01 g/mol = 2.02 g/mol
- Molar mass of O: 1 x 16.00 g/mol = 16.00 g/mol
Now, adding these together:
12.01 g/mol + 2.02 g/mol + 16.00 g/mol = 30.03 g/mol
Therefore, the molar mass of CH2O is approximately 30.03 g/mol.
