Black holes can have a wide range of masses, from a few times that of the Sun to several billion times. The mass of a black hole is one of the most important factors that determine its properties, such as its size, event horizon, and gravitational pull. Astronomers can measure the mass of a black hole by observing its effects on nearby objects, such as stars, or by studying the motion of stars and gas in the vicinity of a black hole. The largest known black hole is located in the center of the galaxy NGC 4889 and has a mass estimated to be around 21 billion times that of the Sun.

Universe mass
The total mass of the universe is not well defined and cannot be measured directly. However, estimates of its mass have been made based on the distribution of matter and its gravitational effects.
Using various observations, such as the cosmic microwave background radiation, the distribution of large scale structures, and the motion of galaxies, astronomers have estimated that the total mass of the universe is between 10^53 and 10^54 kilograms. This is a vast quantity and is estimated to be equivalent to approximately 10^80 protons.
It's important to note that this is only the total matter and energy content of the observable universe. Beyond the observable limit, there may be even more matter and energy that we cannot detec
