The electrons that are missing have a negative effective mass. So the holes have a positive effective mass.

What has a lot of mass?
Black holes.
What kind of stars become black holes low mass or medium mass or high mass?
High-mass stars might become black holes, if the remaining matter (after the supernova explosion) is sufficiently large.
How do black holes survive?
it's mass
What is the most common form of black holes in the universe?
Probably stellar mass black holes
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.
Are there different types of black holes?
there are four types of black holes. 1. super massive 2. Intermediate mass 3. Stellar mass 4. Micro
Do medium size stars become black holes?
No. They do not have enough mass to become black holes. Depending on the mass they will either become white dwarfs or neutron stars.
Are there black holes the size of stars?
The relevant magnitude is mainly the black holes' mass. Since black holes are the result of collapsing stars, yes, there are black holes with the mass of a star.The diameter is usually taken as the diameter of the event horizon. This diameter is directly proportional to the mass; a supermassive black hole such as Sag A* has a diameter comparable to that of a large star.
Is this true or false pumice is a rock that has many tiny holes where gases were trapped?
true
Is a black hole just a hole in space that contains no matter?
No. Without matter there would be no black hole. The black holes confirmed to exist so far actually have a fairly large amount of matter (or mass) - at least 2-3 times the mass of our Sun. The largest black holes have millions or even billions of times the mass of our Sun.No. Without matter there would be no black hole.

Effective mass of holes?
Very large usually but it ranges a lot from between the mass of the moon to 100,000 or more mass of the sun.
How are supermassive black holes different from stellar mass black holes?
In their mass. a "stellar black hole" has a few solar masses (a few times the mass of our Sun), while a supermassive black hole (found in the center of most galaxies) typically has a mass of millions or billions times the mass of our Sun.
