OE. 3 to 1

For example, the compound ammonia always has three hydrogen atoms for every nitrogen atom. This is a 3 to 1 ratio of hydrogen to nitrogen. This same 3:1 ratio holds for every sample of ammonia, under all physical conditions.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
