Homework Help: Atomic volume to Nuclear volume. Problem Solving. PLS HELP!

  1. Oct 4, 2009 #1
    Q: An average dimension for the radius of an atom is 1.0 x 10^-8 cm, and the average radius of the nucleus is 1.0 x 10-^13 cm. Determine the ratio of atomic volume to nuclear volume. Assume that the atom is spherical. [V=4/3(pi)r^3]

    I already have the volume for both, but how can I determine their ratios?

    "Ratio of A to B" means A/B.

    You want atomic volume/nuclear volume then divide.
