comment What is the relation between entropy and mass of black hole?
,thanks,but is it impossible to estimate then low bound of a macroscopic system with given mass?If the low bound of a macroscopic system with given mass equals to the entropy of black hole,the answer is positive,otherwise negative

comment What is the relation between entropy and mass of black hole?
it's entropy is the smallest one among systems with the same amount of mass to it.But maybe this assertion is wrong,since I have just read a post about rotating black hole's entropy.

@Danu, Yes,I know,and I have rephrased it,but I am not sure if it is clear to you now.

comment What is the relation between entropy and mass of black hole?
Thank you.Is the entropy of black hole is minimal among system with the same mass?Does this means mass is equivalent to entropy in the extremely simple case?
