Why is there an upper mass limit for main-sequence stars of about 100 solar masses?

Objects above this mass fuse hydrogen too rapidly and cannot stay together.

Why is there a lower mass limit of 0.08 solar-masses for main-sequence stars?
Below about 0.08 solar masses an object will not be able to ignite nuclear fusion. There may be small amounts of deuterium fusion, but it is not sustainable. Objects between 0.08 solar masses and about 13 Jupiter masses are called brown dwarfs.
What is the difference between stars that become white dwarfs stars that become neutron stars and stars that become black holes?
The difference is in mass. Low to medium mass stars (up to about 8-10 solar masses) become white dwarfs. Massive stars (10 to 25 solar masses) become neutron stars. Stars above 25 solar masses tend to become black holes.
What is the weight of star?
Stars do not have weight they have mass. Our Sun is said to be one solar mass or 1.98892×1030 kg. There are stars smaller than our Sun (read dwarfs) which can be down to 0.075 solar masses and stars much much bigger than the Sun (Hypergiants) which can reach 80-150 solar masses.
How big are most stars?
Most stars are red dwarfs which range from half the mass of the Sun, down to about 0.075 solar masses.
Does 600 billion solar masses equal to 600 billion stars?
Not necessarily. In simplest form, 600 billion solar masses simply means that something is 600 billion times more massive than the sun, regardless of what it is. The sun is more massive than the average star, so if we are talking about stars alone, then 600 billion masses would be equivalent to more than 600 billion stars. It would also depend on what the context is. For example if a galaxy is 600 billion solar masses, much of that mass would be in interstellar gas and dust clouds in addition to stars.

What happen to a large star?
Supernova. Stars below nine solar masses become white dwarfs, though stars more than 1.4 solar masses (Chandrasekhar limit) should nova during their life time. http://en.wikipedia.org/wiki/Supernova http://en.wikipedia.org/wiki/Chandrasekhar_limit

Does 1 billion solar masses equal to 1 billion stars?
Not exactly; stars come in different sizes; or in this case, different masses. In fact, the large majority of stars are red dwarves, which are smaller - and less massive - than the Sun; therefore, I would suspect that a billion stars (randomly selected - or perhaps all the stars in a small galaxy) would have a bit LESS than a billion solar masses. A "solar mass" is simply a convenient way to visualize large masses; for example, for a supergalactic black hole, "a billion solar masses" is easier to visualize than "2 times 10 to the power 39 kilograms".

Which stars are giant stars?
Supergiants are the most massive stars, occupy the top region of Hertzsprung-russell diagram . Supergiants can have 10 to 70 solar masses and luminosity up to hundreds of thousands times the solar luminosity and because of their large masses they have lifespan of few million years and may be less than this value .
What may the collapsed core of a supergiant star form?
What the core of the star will become is dependent of the mass of the supergiant star. Stars between about 3 and 10 solar masses will generally become neutron stars. Stars above 10 solar masses generally become black holes.

How long does Helium Flash in Stars Solar Masses last?
The helium flash only last for a couple of minutes.
What unit do astronomers use to measure the masses of stars and star like objects in the universe?
The official unit for mass in science (and elsewhere), of course, is the kilogram. In astronomy, for ease of comparison, the masses of stars, and even galaxies, are often expressed in "solar masses", meaning multiples of the mass of our Sun.
How big is the stars in your galaxy?
Our galaxy, the milky way, has stars much bigger than our sun. Our sun is considered one solar mass in it's size. The Milky Way has star that range from 1/2 a solar mass to 50 or 100 solar masses.
