According to NASA, about 4.6% of the total mass in the universe is composed of atoms.
I'm not 100% certain that I believe that's literally true; I think it's an oversimplification and that when they say "atoms" they really mean "normal matter" including neutrinos and the like.
Still, it's the best answer I could find. We still don't know what the masses of neutrinos are, we just know that they're too small to measure and that they can't be precisely zero.

What is your mass on other planets?
Mass is a measure of how much matter there is. Therefore your mass will remain constant on Earth, in space or anywhere in the universe. (unless you go on a diet)
How much does the universe weigh in kg?
Universe has no weight because it has no Gravitational force
How much pounds does the universe weight?
It ways infinity because the universe is infinite
Which is the oldest the sun moon or earth?
Matter cannot be created or destroyed it only changes forms. They are all the same age.
How much argon is in the universe?
Its abundance is 0.02%
Is atoms is matter?
Presumably that refers to matter that is made up of atoms. Most matter in your everyday life is made up of atoms, but in our Universe, there is about 5 times as much matter that is NOT made up of atoms - the so-called dark matter.
How do you write a sentence with incaculable it?
Most people believe the number of atoms in the universe is incalculable because nobody knows how much matter is in it.
How much of the universe is matter?
The real question is how much of the universe's matter is this dick.
What is the universes most common matter?
According to current estimates, the mass in the Universe is made up of: * 68% dark energy. Not much is known yet about this type of substance. * 27% dark matter. Not much is known about this type of substance, either. * 5% regular matter - matter of known composition. Most of the regular matter is in the form of atoms; and most of it is in a state of matter known as a plasma.
Are elements in all things?
No. An element is a group of the same kind of atoms. Compounds and mixtures contain different kinds of atoms, and thus, different kinds of elements.However, there are several things that are not made up of atoms. This includes light, different kinds energy, neutron stars, black holes... and the mysterious dark matter. The Universe contains at least 5 times as much dark matter, than atoms and other kinds of known matter.
How did the Universe get from the big bang to now?
The universe have been expanding since the big bang. After the first 200 seconds after the creation of the universe, the universe was the size of galaxy. Now how much the universe size is nobody can measure It is also said that a lot of matter and antimatter have been destroyed since then. In the first few moments of the universes creation, particles called quarks were formed. They soon fused to create the first atoms called hydrogen and helium. Larger atoms such as beryllium, oxygen and carbon were formed by the nuclear reactions inside stars. Even bigger atoms were formed due to the shock waves inside the stars such as tungsten or osmium. But all this took a lot of time to happen.
What might much of the mass of the universe be composed of?
The universe is made mostly of dark matter and dark energy, and we don't know what either of them is.
Why can only four atoms of phosphorus produce only two molecules of diphosphorus trioxide even when there is an excess of oxygen atoms?
Because no matter how much oxygen there is, it is diphosphorus, so each molecule has two phosphorus atoms. Because no matter how much oxygen there is, it is diphosphorus, so each molecule has two phosphorus atoms.
What is matter in the universe?
Dark matter is matter of an unknown type. It is known to exist, due to its gravitational influence, but it is not known what it is made of. There is at least 5 times as much dark matter than "normal" matter.
How much is the universe expanding by right now?
The Universe is expanding. That is, it is getting bigger.The Universe is expanding. That is, it is getting bigger.The Universe is expanding. That is, it is getting bigger.The Universe is expanding. That is, it is getting bigger.
What is the observational evidence that maybe as much as 95 of the matter in the universe is as yet undiscovered?
Measurements in the early 60's of the motion of galaxies in clusters discovered a discrepence, there was too much gravity for the number of galaxies counted which is known as the dark matter problem Further observations showed that dark matter is the dominate form of matter in the Universe, up to 95% of the Universe is composed of dark matter, yet its identification has eluded us source:http://zebu.uoregon.edu/~js/21st_century_science/lectures/lec23.html
A measure of amount of matter?
Mass is the amount of matter in a sample of a substance. Mass translates directly to how much matter is in something, in other words, how many atoms are crammed into it.
