Alcohol, you mean ethanol (spirit) I suppose, is C2H5OH
Water : H2O

Propyl alcohol is a compound, not an element, and therefore has a formula, not a symbol; its molecular formula is C3H7OH. It has two isomers called "normal" and "iso" propyl alcohols by most American chemists but 1-propanol and 2-propanol internationally or by Americans in formal papers.
Water, ethyl alcohol, propyl alcohol, oil. Water has the highest specific gravity followed by ethyl alcohol, propyl alcohol, and oil, which has the lowest specific gravity.
The chemical symbol for ethanol is C2H5OH. Water does not have a chemical symbol, but its chemical formula is H2O.
When water is added to alcohol, it lowers the overall alcohol content of the mixture. This process is known as dilution and results in a beverage with a lower alcohol percentage than the original alcohol content.
The chemical symbol for isopropyl alcohol is C3H8O.
C25oh
"Alcohol" is actually a general term for any compound containing an -OH (hydroxyl) group bonded to a carbon which itself is bonded only to hydrogens and other carbons. In common conversation, alcohol refers to drinking alcohol, or ethyl alcohol, abbreviated EtOH. It has the chemical formula C2H5OH.
-OH
In plain tap water, there is no alcohol. There is no alcohol present in any water unless it is labeled that there is alcohol in water. Alcohol can be dumped into the ocean, and then alcohol would be in water, but generally, there is no alcohol in water.

There is no symbol for rain water.
Either way is safe, provided you are getting the correct proprtion or mixture required.
Water mixed with alcohol is lighter than fresh water because alcohol is less dense than water. When alcohol is added to water, the overall density of the mixture decreases due to the lower density of alcohol, making the mixture lighter than fresh water.
Water contains no alcohol or oils, as rubbing alcohol does.
Propyl alcohol is a compound, not an element, and therefore has a formula, not a symbol; its molecular formula is C3H7OH. It has two isomers called "normal" and "iso" propyl alcohols by most American chemists but 1-propanol and 2-propanol internationally or by Americans in formal papers.
As more alcohol is added to water, the solubility of alcohol in water generally increases. This is because alcohol molecules can form hydrogen bonds with water molecules, making it easier for the alcohol to dissolve. However, there may be a limit to how much alcohol can dissolve in water depending on the type of alcohol and temperature.
