Answer:

Cygnus X-1 21 is the heaviest stellar hole to be discovered. Cygnus X-1 21 weighs 21 times as the sun's mass. Scientists previously assumed wrong, it is around 1.5 times heavier then the last estimate. Cygnus X-1 21 was discovered by scientists using VLBA (Very Long Baseline Array.) This was discovered without gravitational waves which is usually used in science.

The network is 10 radio dishes and ranges to the United States, from Hawaii to the Virgin Islands. VLBA was responsible for tracking radio-bright jets of material flowing out of Cygnus X-1’s black hole for six days straight. Cygnus X-1 is around 7,200 light-years from Earth, which contradicts the last estimate of 6,000. The measurement for this new discovery gives astronomers a tough challenge in their understanding of black holes. Theres more to come in science with each discovery made.

The question is incomplete , the complete question is;

The mass of each Wt isotope is measured relative to C-12 and tabulated below. Use the mass of C-12 to convert each of the masses to amu and calculate the atomic mass of Wt.

Wt-296 = 24.6622

Answer:

The atomic mass of Wt-296 is 195.9464 amu.

Explanation:

1 amu is defined as 1 by twelfth of the carbon-12 mass.

Mass of an isotope Wt-296 = 24.6622

Mass of an isotope Wt-296 in amu = M

$M\times \frac{1}{12 amu}=24.6622$
