How much mass would even the smallest of black holes have to absorb (keeping also in mind the radiation lost as it grows) to obtain its size?(adsbygoogle = window.adsbygoogle || []).push({});

And considering the largest Black holes discovered so far, how much mass would it have had to gobble up to get to that size?

On the average, how much mass is there in an average galaxy? or even that of galactic dust clouds?

And lastly, given the rate of evaporation due to (I think its called Hawkings radiation) venting, how long would it take even the smallest black hole to vanish? (or would it after a point not be large enough to lose its own mass due to the venting)?

Added preponderance: If a black hole is so dense, How could the hawkings radiation escape through the mass? I am not talking gravity, but instead Its packed density.

Thank you.
