Answer:
The statements "A solar mass is equal to the mass of the Sun", "Most stars are smaller than the Sun" and "There are some stars much larger than the sun, up to 100 solar masses or more" are correct.
Step-by-step explanation:
Solar mass is a unit of measurement used to comparatively measure the mass of stars and other very massive astronomical objects such as galaxies. It is equal to the mass of the Sun and is equivalent to about 332,950 times the mass of the Earth. So, the statement "A solar mass is equal to the mass of the Sun" is correct.
On the other hand, a star consists of a luminous plasma spheroid supported by its own gravity. The closest star to Earth is the Sun. Not all stars are the same size. And as his life progresses, the size of the stars changes. To know its size, the mass and diameter must always be taken into account. The latter is the one that varies continuously, while the mass is usually constant.
The sun is a medium-sized star, and being the best known star, it is used as a reference to know the size of the stars. There are stars larger and smaller than their size. Stars have been found that are 100 times larger in diameter than the sun. Also stars that are only one tenth of their size. Most are smaller than the sun.
Then, the statements "Most stars are smaller than the Sun" and "There are some stars much larger than the sun, up to 100 solar masses or more" are correct.
