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.
yes and no depends on size of hole :]
The size of a black hole, as defined by the size of the event horizon, depends on the mass of the black hole and its electrical charge. The diameter of the event horizon is directly proportional to the black hole's mass. Adding electrical charge decreases the size of the event horizon.
Firstly our sun is too small to become a black hole. Only stars that are a million to a billion times our sun do this, because they burn through their fuel quickly, unlike our sun. A typical black hole has 3 times the mass of our sun
You would have a black hole the size of the combined mass of the two black holes.
One common term used is black hole evaporation. This relates to a mechanism wherein the black hole's mass is gradually lost through Hawking radiation; but the rate of loss is inversely proportional to the black hole's size and thus accelerates as it shrinks. At the moment it vanishes it is thought to do so with a burst of gamma radiation; the Fermi space telescope is intended to search for such gamma flashes.
A black hole's size is determined by its mass, which is the amount of matter it contains. The more mass a black hole has, the larger its size. The size of a black hole is typically measured by its event horizon, which is the point of no return where gravity is so strong that not even light can escape. The event horizon's size is directly related to the mass of the black hole.
Any matter that enters the black hole will be destroyed. Also, it will increase the black hole's size.
A black hole can definitely get to the size of a planet. The width of the largest known supermassive black hole is thought to be over ten times the size of the entire orbit of Neptune around our Sun.
No.
yes and no depends on size of hole :]
A black hole? well scientist are not sure. Black holes is a theory, not proving to be true. But there could be.

The size of a black hole is determined by its mass, with smaller black holes having a smaller size. The gravitational pull of a black hole is incredibly strong due to its mass being concentrated in a very small space, creating a powerful gravitational force that can even trap light.
There isn't one. It depends on how much matter the collapsed star (black hole) has gathered.
