Matter is made of atoms, vast collections of atoms.
Differences in matter are due to different amounts of protons and neutrons in the atom. Elements are distinguished by the number of protons, whereas isotopes (same element but different mass) are determined by the number of neutrons.
The most abundant gas in the universe is hydrogen. Hydrogen atoms make up about 75% of the universe's elemental mass.
The total mass of outer space, often referred to as the mass of the universe, is estimated to be around (1.5 \times 10^{53}) kg. This includes both visible matter, such as stars and galaxies, and dark matter, which makes up about 27% of the universe's total mass-energy content. Additionally, dark energy constitutes about 68% of the universe, contributing to its overall dynamics but not its mass in the conventional sense. However, precise measurements remain challenging due to the vastness and complexity of the universe.
The total mass of the universe is estimated to be about 10^53 kilograms, which includes both visible matter (like stars and galaxies) and dark matter. However, the weight of the universe is not typically defined since weight depends on the gravitational force acting on mass, which varies depending on location. Additionally, dark energy, which makes up about 68% of the universe, complicates calculations as it does not have mass in the conventional sense. Thus, while mass can be estimated, the concept of weight is less applicable on a cosmic scale.
The most abundant element in the universe is hydrogen. It makes up about 74% of normal matter by mass.
Water makes up about 0.0001% of the total mass of the universe. This includes water vapor in the atmosphere, water in comets, asteroids, and icy planets.
The most abundant gas in the universe is hydrogen. Hydrogen atoms make up about 75% of the universe's elemental mass.
Most of the mass of visible matter in the universe is composed of baryonic matter, which includes ordinary atomic particles such as protons, neutrons, and electrons. This baryonic matter primarily forms stars, planets, and galaxies, with hydrogen and helium being the most abundant elements. Additionally, a significant portion of this mass is found in interstellar gas and dust. However, it is important to note that visible matter constitutes only a small fraction of the total mass-energy content of the universe, with dark matter and dark energy making up the majority.
Dark matter. It is theorized to make up approximately 27% of the universe's total mass-energy content. Its presence is inferred from its gravitational effects on visible matter.
Hydrogen is the element that makes up most of the detectable mass in the universe. About 75% of the normal matter in the universe is hydrogen.

Hydrogen makes up about 75% of the universe by mass. It is the most abundant element in the universe and can be found in stars, gas clouds, and planets.
Of all the baryonic matter, aluminium makes up about 0.005%. Considering that ordinary baryonic matter makes up about 4.9% of the universe, that would make aluminium constitute about 0.049 x 0.00005 = 0.000000245% of the mass of the universe.
In terms of the total mass of the universe, it is single elements.
The most abundant element in the universe is hydrogen. It makes up about 74% of normal matter by mass.
Plasma. It makes up more than 99% of visible matter in the universe, and most of the invisible matter.
Water makes up about 0.0001% of the total mass of the universe. This includes water vapor in the atmosphere, water in comets, asteroids, and icy planets.
