Question

Atmospheric nitrogen is about 0.5% denser than chemical nitrogen.

• A. True
• B. False

Answer 1

The correct option is A True

• Atmospheric nitrogen is heavier than chemical nitrogen because of the presence of Argon as a contaminant.
• Argon's presence in the atmosphere contaminates nitrogen,
• Since argon has a mass of 40 gm compared to nitrogen 28 gm mass.
• So it will make atmospheric nitrogen heavier compared to chemical nitrogen.

Therefore, Atmospheric nitrogen is about 0.5% denser than chemical nitrogen is true.
