It should be zero. We can use as DO standard solution instead of 2.0 M sodium sulphite (because 2.0 M Na2SO3 DO is zero). Refer to the following link below.

Boiling should drive out all of the dissolved oxygen, leaving the entirety of the water to consist of H2O. The weight percentage of oxygen in this compound is approximately 100(16/18) = 89 %.
As the depth increases, DO decreases up to 2000 to 3000m. But then it increases again as the depth increases. See the link below..
Even boiled distilled water will still have oxygen, but the oxygen will not be in elemental form as a dissolved gas.
If both t etap water and the distilled water are open to the air and both have dissolved oxygen then the iron nail will rust faster in tap water. Rusting requires dissolved oxygen and goes faster if there are dissolved salts.
As it don't have dissolved salts ***** Distilled water does not conduct electricity for the above reason.
Dissolved Oxygen is the bubbles in water when you splash there's bubbles in the water that is Dissolved Oxygen.
oxygen is dissolved in water and is also important for the survival of aquactic animals and plants
It should be 0.
Even boiled distilled water will still have oxygen, but the oxygen will not be in elemental form as a dissolved gas.
The dissolved oxygen in the water reacts with the nail to form rust.
Yes, provided there is oxygen dissolved, which will be the case if the distilled water is open to the air, a rusting reaction will take place. It will be slow. The reaction is much quicker when there are dissolved salts.

An iron nail will rust slowly in distilled water when that water has dissolved oxygen. If you get rid of the oxygen by boiling and keep it from getting back in then the iron nail will not rust at all.
The oxygen dissolved in water is a measure of dissolved oxygen (DO).
Both are made up of 2 hydrogen atoms bonded with an oxygen atom. The difference is that distilled water is pure water, saline or salty water has sodium chloride dissolved into the solution.
Yes, when is dissolved (not distilled) in water or when is melted.
The Goldfish will die if put in distilled water, this is because distilled water has a lack of bacteria, dissolved salts and Oxygen. Goldfish have gills so that they can extract oxygen from water, without this dissolved Oxygen, the fish will die.
As it don't have dissolved salts ***** Distilled water does not conduct electricity for the above reason.
We do not breathe in the water as we can't breathe dissolved oxygen.Dissolved oxygen are oxygen that are dissolved into the water.
