Because radius of a black hole varies directly with mass (twice the mass means twice the radius) per r = 2Gm/(c^2), and the volume varies with the cube of the radius (per v = (4/3)*pi*(r^3) ...) (twice the radius is eight times the volume) there will indeed be a theoretical black hole whose density is equal to water (one gram per cubic centimeter, or one thousand kilos per cubic meter). Since density is mass divided by volume, this becomes an exercise in solving mass for that density.
I calculate a mass of about 3.03 x 10^38 kg, or around a hundred and fifty million times the Solar mass.. which would give the black hole a radius of roughly(!) 450 million km, or about 3 times the distance of the Earth from the Sun. Can somebody else check my calculations please :)
Density is equal to the mass divided by the volume.
No mass does not equal density divided by volume but means multiplied by because that is six dimensional space and density is three dimensional space and mass volume is -3 dimensional space
Any extensive quantity divided by volume is called that quantity density .A baby's mass is small, a baby's volume is small ; but its average mass density (mass divided by volume) is the same as for anyone - anyone composed of the same materials, in the same fractions.
Density is equal to mass divided by volume. As mass increases so does volume so this is a direct relationship.
Since Density is equal to mass divided by Volume... D=M/V Then... The density would equal 5.667 g/cm3
No, mass divided by volume equals density.
Not exactly. Density is weight divided by volume.
