Question

The correct match for atmospheric gases is

• A. Nitrogen- 0.03%, Oxygen- 20.95%, Argon- 0.93% and Carbon dioxide-78.08%
• B. Nitrogen- 78.08%, Oxygen- 20.95%, Argon- 0.93% and Carbon dioxide- 20.02%
• C. Nitrogen- 0.03%, Oxygen- 0.03%, Argon- 20.95% and Carbon dioxide- 1.02%
• D. Nitrogen- 78.08%, Oxygen- 20.95%, Argon- 0.93% and Carbon dioxide- 0.03%

Answer 1

The correct option is D Nitrogen- 78.08%, Oxygen- 20.95%, Argon- 0.93% and Carbon dioxide- 0.03%

By volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases.

So, the correct answer is option D.
