A black hole does NOT have infinite mass. What it does have is a huge amount of mass compressed into so small a diameter that there exists a certain limit near its surface where the escape velocity exceeds the speed of light. This limit is called the event horizon; matter and light falling within this limit will never escape it.
Some cosmologists theorize a black hole's mass can be so dense, the matter is compressed until it has zero, or even negative diameter. This is what's called a singularity: mass with no dimensions.
But let's keep in mind it's just a theory. No one can actually look inside the event horizon to see what's really there. For the time being, singularities only exist mathematically.

If a black hole could exist it would be a 2 to 3 solar mass body with a diameter of about 3 km.
The surface gravity is so intense that nothing, not even light can escape.
As theory has it the entire mass of the body would be compressed into a point with no dimensions in space.
The singularity is controversial in that the point would have to be infinite,an infinite entity in a finite universe.
There are a few good reasons why a black hole can't exist.

Unfortunately no one knows.
A black hole has such a large amount of mass that the light that it emits, and the light emitted by objects around it, is pulled towards the black hole by its gravity. (Remember that light has the properties of both a wave and a particle). Since this light can't escape a black hole, no one really knows what's there, only that it is an unimaginably dense piece of matter.

From the math, the singularity is a point of infinite mass density.

Actually, the singularity is a mathematical result that has infinite mass in a zero volume sphere.

black hole ? , or or or , do you mean a STAR GATE and if by that's then i do no ; and to your black hole , if that it's was : could be and maybe there was a single black sun ???, and also to how much mass that it's had : i do no , but , also maybe you can refer it to the our only known single sun in which they said there was a big bam-boom masses to it's ???.
