One molecule of oxygen has the same mass as
Correct answer: D. One atom of Sulphur
- A. 8 moles of O2
- B. 16 moles of H
- C. 2 molecules of CH
- D. One atom of Sulphur
Explanation
One molecule of oxygen (O2) has a molecular mass of approximately 32 atomic mass units (amu). Therefore, it corresponds to 32 grams per mole. A gram atom of sulfur also has a mass of 32 grams because the atomic mass of sulfur is 32, making it equivalent to one molecule of oxygen in terms of mass. The other options are incorrect because they either involve incorrect mole-to-mass calculations or involve molecules that do not match the molecular mass of oxygen's single molecule.
