I am assuming that 99pm means pico meters, so 99pm = 99 x 10^-7 cm
D=mass(g)/volume(cm3)
Plug in the value for radius into the equation to solve for the volume which will have units of cm^3
v=4/3πr^3
Since density=mass(g)/volume(cm3),
Solve for density,
D= (5.89 X 10^-23 g/volume calculated in cm^3)
so to get volume, you do v=(1.33)*3.14*99e-7^3????
Yes.
But, I gave you the wrong units for 99pm in cm, it should be 99x10^-10. I apologize about that
