Gravity of a star = Mass of a star?

[Majinere566]

Hello, I need help with something

So in hitman reborn enma launches these gravity spheres which is stated to have the gravity of a star and he's able to collapse em into black holes.

Apparently Gravity is directly proportional to mass, so would that mean that it has the mass of the sun

Or

Does it keep the same mass when turned into a black hole?

Or is there any other alternatives to finding their masses?

I don't know what to do I need help

Anyone?

Apparently Gravity is directly proportional to mass,

Gravity is factor of density and mass. Not just pure mass.

Or is there any other alternatives to finding their masses?

Well, there are ways to find it through some gravitational constant calculations. But nothing that would be better thsn the existing black hole calcs.

How do I find that, and yeah I know I'm only doing this for supporting feats

How do I find that

The forumla is M = gr^2/G, where M = Mass in kilograms, g = gravitational acceleration, r = radius from core in meters, and G = universal gravitational constant.

So I did something like this
M=gr^2/G
274×3.41^2/6.6743 × 10^-11 and I got 4.77368323e-9???

You did your PEMDAS incorrectly

• M = 274 * 3.41^2 / 6.6743e-11
• M = 3,186.0994 / 6.6743e-11
• M = 47,736,832,326,985 Kilograms
