No stars are expected with masses greater than 150 times our sun because?

All stars are in a balance between gravity crushing them in, and the pressure caused by nuclear fusion at the star's core. And the bigger the star, the greater the amount of energy generated.
At some point, the pressure of the stellar fusion is SO powerful that the outer layers of the star are blasted off into space. That point, we believe, is at about 150 solar masses.

What mass is required for a Type ll supernova?
Stars with a mass about 9 solar masses, or greater, will explode as a type II supernova.
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.
Where is the barycenter located when binary stars have similar masses?
somewhere between the stars
What is the final stage for stars whose final masses are greater than three times the mass of the sun?
Stars more than about 3 times the mass of the sun are likely to wind up as neutron stars. Stars more than about 10 times the mass of the sun will probably end up as black holes.
What affect does gravity have on all matter in the universe?
Because of the existence of 'gravity', there are a pair of equal forces between every two specks of mass in the universe. Greater masses and smaller separations result in greater forces. These simple facts lead to the formation of galaxies, stars, and planets, and to virtually all of the motions we see, including orbits.
Why are there no stars with masses much greater than 100M?
There are no stars with a mass greater than 100M because they cannot be sustained. Stars this size usually explode in a supernova or suddenly collapse.
Where in the universe are heavy elements with masses greater that that of helium being produced today?
In the interior of certain massive stars.
What mass is required for a Type ll supernova?
Stars with a mass about 9 solar masses, or greater, will explode as a type II supernova.
Why do planets orbit stars and moons orbit stars?
Because stars have a greater amount of gravity
Why are the sun and stars attracted to each other even though they have same charge and mass?
They are attracted to one another by gravity, which is not affected by electrical charge. Gravity is an attractive force that occurs between all objects with mass. You don't have positive and negative masses that attract and repel. The greater the mass, the greater the attraction. Second, the stars do not all have the same mass. The masses of stars vary considerably.
What are Binary stars used to determine?
The masses of the two stars.
Why can you see the stars when the sky is dark?
Because during the day - the Sun's luminosity is greater than the stars.
What is a stars mass?
This is too broad. All stars have different masses.
Where is the barycenter located when binary stars have similar masses?
somewhere between the stars
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.
Why do stars with smaller masses burn longer than stars with larger masses?
Stars with larger masses have stronger gravity; this results in more pressure; which in turn makes the star hotter. As a result of the higher temperature, they will shine brighter, and burn their fuel much faster.
Are eclipsing binary stars better for determining masses than non-eclipsing binaries?
Yes, because it is easier to determine the precise times of their mutual orbits, which allows us to calculate their masses.
