Sodium Chloride is an ionic compound and ha a high hydration energy. Hence, it is highly soluble in polar solvents like water, But it is not very soluble in gasoline since gasoline is a non-polar solvent.
Hexane and gasoline both are insoluble in water.
It is highly water soluble (hydrophillic) related to it's polarity. It is a polar molecule, meaning it has a partial negative and a partial positive side, and therefore the negative portion of ammonia (Nitrogen) would attract the positive portion of of water (hydrogen), and the positive portion of ammonia (hydrogen) would attract the negative portion of water (oxygen).
