## Homework Statement

A hydrogen atom has a diameter of approximately 1.06x10^-10 m, as defined by the diameter of the spherical electron cloud around the nucleus. The hydrogen nucleus has a diameter of approximately 2.40x10^-15 m.

(a) For a scale model, represent the diameter of the hydrogen atom by the length of an American football field (100 yards = 300 ft) and determine the diameter of the nucleus in millimeters.

(b) The atom is how many times larger in volume than its nucleus?

## Homework Equations

2.40x10^-15 (1000mm/1m) = 2.40e-12

V=(4/3)*pi*r^3

## The Attempt at a Solution

For (a) I got 2.40e-12

It says "Your response differs from the correct answer by orders of magnitude."

For (b) I got 4.42e4

It says "Your response differs from the correct answer by orders of magnitude."

Any help would be greatly appreciated!!
