Atomic and molecular sizes are typically of the order of a few Angstroms. Assuming that a `N_2` molecules is spherical in shape with radius `(r) = 2 xx 10^(-10)` m, calculate
the percentage of empty space in one mole of `N_2` gas at S.T.P.

Explanation

To calculate the percentage of empty space in one mole of \( N_2 \) gas at standard temperature and pressure (S.T.P.), we will follow these steps:

### Step 1: Calculate the Volume of One Molecule of \( N_2 \)

Assuming the \( N_2 \) molecule is spherical in shape, we can use the formula for the volume of a sphere:

\[
V = \frac{4}{3} \pi r^3
