Question

Help!! The Proton has a mass of 1.67 x 10^-24g and a diameter of 1.000 x 10^-13. Calculate the density of the nucleus assuming it so be spherical in shape.

Answer 1

density = Mass/volume
Volume of Sphere is \[4/3pir ^{2}\]
r= d/2

Answer 2

where did the 4 come from?

Answer 3

its formula of Volume of sphere = (4/3) [pi] r3

Answer 4

ops the above one is cube ,not square
\[4/3pir ^{3}\]

Answer 5

Now just put the values ^_^
