About 75% of the Sun's mass is Hydrogen, 23% is Helium and the remaining 2% consists of heavier elements such as carbon and oxygen.
The space that a gas takes up is called its volume.
the carbon rises from the gas therefore lightening it, the mass will only reduce by a small fraction, but it will.
The short answer is yes, gas has mass and density. However, you should note that gas is a state of matter, just as solid and liquid are. Since all matter has mass, any substance in its gaseous state has mass. Since all matter occupies space, it has density, since density is defined as mass per unit volume, where volume is space. Larger objects dont always have more mass than smaller objects.
Such an object makes a larger dent in the fabric of space-time than an object with little mass. (It has a greater gravitational attraction than less massive objects)A greater force is required to accelerate such an object than a less massive object
The rate of diffusion of a gas depends on the weight of the gas molecules. The heavier the molecules, the slower they move - the lighter the molecules, the faster they move. Nitrogen molecules weigh about 28 units. Chlorine molecules weigh 71 units. So we would expect nitrogen to diffuse more quickly than chlorine.
Hydrogen.
It is a very bright mass of roiling gas or plasma.
helium is the gas which makes most of the sun
the suns a gas
nuclear fusion
Primordial Mass and Energy.Everything we and the planets are made of came from a sun at one time or another. Hot gas from the sun cools and becomes dust, that collects into molecules and eventually rocks which all form ed the planets, asteroid and such by the force of gravity collecting them together.Even suns are made up of other suns. The only suns that were not are population 1 suns - which coalesced out of the gasses of the universe until the pressure ignited it.
Hydrogen
Most of the sun s mass lies in the hydrogen gas present in it
Nitrogen is the most common gas in the earth's atmosphere.
star is a huge mass of gas, where as earth is a planet
Helium
It is the most abundant gas in our atmosphere. It makes all life, just like carbon. Its atomic number is 7 Its atomic mass is 14
