100 gm of water can dissolve as much as 52.9 gm of ammonia at 20 degree Celsius and 1 atm pressure. A solution of ammonia in water is called ammonium hydroxide, NH4OH. Ammonia's high solubility in water is due to hydrogen bonding with water molecules.

Understanding Gas Solubility in Water
Gases vary significantly in their solubility in water, influenced by molecular properties and interactions. Among the options given, ammonia stands out as the most soluble gas at room temperature.
Key Factors Influencing Solubility:
- Polarity: Ammonia (NH3) is a polar molecule, which enhances its interaction with the polar water molecules. This polarity allows ammonia to dissolve readily.
- Hydrogen Bonding: Ammonia can form hydrogen bonds with water, leading to increased solubility. Each ammonia molecule can form up to three hydrogen bonds, effectively integrating into the water structure.
- Molecular Weight: Ammonia has a relatively low molecular weight, which generally facilitates its movement and interaction with water molecules, enhancing solubility.
Comparison with Other Gases:
- Nitrogen (N2): This gas is nonpolar and has low solubility in water due to its inert nature and inability to form significant interactions with water.
- Nitrous Oxide (N2O): While slightly more soluble than nitrogen, it is still not as soluble as ammonia. Its polar character is weaker compared to ammonia.
- Carbon Dioxide (CO2): CO2 has moderate solubility in water and can form carbonic acid when dissolved. However, it does not match the high solubility of ammonia.
Conclusion:
In conclusion, ammonia's polarity and ability to form hydrogen bonds with water make it the most soluble gas in the options provided. This property is crucial in various applications, including agriculture and environmental science, where ammonia is used as a fertilizer and in wastewater treatment.
