What is the ratio of nitrogen and hydrogen in ammonia on the basis of mass?

Correct option is B

The correct answer is (B) 14 : 3.

Explanation:

• Ammonia (NH₃) consists of 1 nitrogen (N) atom and 3 hydrogen (H) atoms.
• The atomic mass of nitrogen is 14, and the atomic mass of hydrogen is 1.
• The mass ratio of nitrogen to hydrogen in ammonia is:14:(3×1)=14:314 : (3 \times 1) = 14 : 3

Information Booster:

• Ammonia (NH₃) is widely used in fertilizers due to its high nitrogen content.
• Plays a critical role in the nitrogen cycle, helping plants absorb nitrogen.
• Used in industrial applications, including refrigeration, cleaning agents, and pharmaceuticals.
