Empirical Weight of CH2O2 with Molecular Mass 300g

Explanation:

1. Definition:
- The empirical weight of a compound is the sum of the atomic weights of all the elements present in the compound's empirical formula.

2. Calculation:
- The molecular formula of CH2O2 can be simplified to its empirical formula, which is CHO.
- The atomic weights of carbon (C), hydrogen (H), and oxygen (O) are approximately 12, 1, and 16, respectively.
- Therefore, the empirical weight of CHO would be 12 (C) + 1 (H) + 16 (O) = 29g/mol.

3. Relationship between Molecular Mass and Empirical Weight:
- The molecular mass of CH2O2 is given as 300g.
- To find the empirical weight, we need to divide the molecular mass by the empirical formula weight.
- Therefore, the empirical weight of CH2O2 with a molecular mass of 300g would be 300g / 29g/mol ≈ 10.34.

4. Conclusion:
- The empirical weight of CH2O2 with a molecular mass of 300g is approximately 10.34g.
