Assume that nucles of f atom is a sphere of radius 5×10 cm. calculate thevdensity of f sphere

density = mass/volume

v = 4pi/3 r^3

I assume you know the mass.

Check your post for the correct radius. I think 50 cm is large for a nucleus. I suspect you omitted the (negative) exponent of 10.

To calculate the density of a sphere, we need to know the mass and volume of the sphere. However, in this case, we only have the radius of the sphere given (5×10 cm). Without knowing the mass or any other information about the nucleus of the fluorine (F) atom, it is not possible to calculate the density of the sphere.

Generally, the density (ρ) of an object can be calculated using the formula:

Density (ρ) = Mass (m) / Volume (V)

But since we do not have the mass or any other information about the fluorine atom nucleus, we cannot proceed with the calculation.
