1 gm mole of methane (CH4) contains_________________?
Correct answer: C. 4 gm atoms of hydrogen
- A. 6.02 x 10^23 atoms of hydrogen
- B. 3.01 x 10^23 molecules of methane
- C. 4 gm atoms of hydrogen
- D. 3 gms of carbon
Explanation
One gram mole of methane is one mole of CH4, containing four gram-atoms of hydrogen because each molecule has four hydrogen atoms. It contains 6.02 × 10^23 methane molecules, not half that number.
