Yes, blackholes do have mass. They take up space, however, it can be argued that it doesn't have mass because it technically doesn't have any weight.

What if 5 black holes meet?
If five black holes came together they would merge to form a single black hole with a mass equal to the sum of the masses of the five original black holes.
How does a black hole have extreme mass?
Not all do - most black holes have masses comparable to that of a star; this makes sense, since they are believed to have formed from collapsing stars. There are, however, black holes that have thousands, millions, or even billions of times the mass of our Sun - called intermediate black holes, or (for about a million solar masses or more), supermassive black holes. It is currently unknown how exactly they got so massive.
What is m60 on black holes?
Not sure what you mean. M60 is a galaxy. Just about all galaxies have supermassive black holes in their center - and lots of smaller black holes. The supermassive black hole in M60 is estimated to have 4.5 billion solar masses - one of the largest known black holes.
What is the mass of the biggest black hole?
That depends. The smallest black holes known are generated by the collapse of massive stars, so the holes themselves tend to be rather massive--on the order of the mass of a star. Most galaxies contain black holes that mass hundreds of thousands to billions of times that of our sun. Sagittarius A, our Milky Way's black hole, is a little over four million solar masses. It is possible quantum black holes formed during the big bang. These would have been tiny singularities, with masses measured on the atomic scale. Stephen Hawking demonstrated fairly effectively such black holes would have preferentially absorbed charged particles from the quantum foam, bleeding mass until they evaporated. It is unlikely any would now be left from 13.7 billion years ago.
How fat is a black hole?
A black hole can have anywhere between a few Sun masses, and several billion Sun masses (the so-called "supermassive black holes"). The diameter of the event horizon, if that's what you mean, is directly proportional to the black hole's mass - in other words, more massive black holes have a larger diameter.
How big is a black hole in outer space so a child can understand the answer?
Black holes actually come in different masses, and therefore sizes.
How does a black holes acquire greatest mass?
Most black holes are stellar mass black holes with masses comparable to those of large stars as they form from the collapse of massive stars. Scientists know of the existence of supermassive black holes that are millions to billions of times the mass of our sun and can be found in the centers of most galaxies. Scientists still do not know how these black holes become so massive.
What is a supermassave black hole?
A supermassive black hole refers to a black hole of considerable mass - usually between around a million solar masses, and several billion solar masses. Such huge black holes are found in the center of all large galaxies.
Have astronomers found evidence of any other black holes in other galaxys?
Yes. In fact, it looks as if all, or most, larger galaxies have huge ("supermassive") black holes in their center. The largest black holes found so far have an estimated 20 billion solar masses.
What is the common size of a black hole?
There is no "average" mass for black holes throughout the entire universe. Black holes range greatly in mass, depending on how they were formed, and how long they have existed if you take Hawking Radiation into account. Mass can be anywhere between a couple hundred protons, such as those created by cosmic rays striking Earth's atmosphere, or an enormous mass such as those in the center of almost every spiral galaxy.
What is the mass range for a supermassive black hole?
Anywhere from about 100,000 solar masses (100,000 times the mass of our Sun), to more than 10 billion solar masses (the approximate size of the largest known black holes).
Why do stellar masses result in black holes?
The only known mechanism to produce a black hole is the gravitational collapse of an object that has at least 2-3 times the mass of our Sun. However, it is considered possible that the enormous densities right after the Big Bang may have resulted in some black holes; for more information, read about "primordial black holes".
