hey /sci/ I got one chance left or i'll get a B :( on this, i got it wrong twice

Use the formula for the Schwarzschild radius Rs to calculate the volume 4/3pi Rs^3 inside the event horizon of a black hole of mass M.

What does the mass of a black hole need to be in order for its mass divided by its volume to be equal to the density of water 1(g/m^3)?

The answer needs to be (answer) *Msun

the schwarxchild radius eq. is M= Gm/c^2

Use some into to Algebra for this into to astronomy stuff x-x.
