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 volume of a single `N_2` molecule,

Explanation

To calculate the volume of a single \( N_2 \) molecule, we will use the formula for the volume of a sphere. The steps are as follows:

### Step 1: Identify the formula for the volume of a sphere
The volume \( V \) of a sphere is given by the formula:
\[ V = \frac{4}{3} \pi r^3 \]
where \( r \) is the radius of the sphere.
