The density of solid argon is `1.65g//mL ` at `-233^(@)C` . If the argon atom is assumed to be sphere of radius `1.54xx10^(-8)cm`, what percentage of solid argon is apparentaly empty space ? `(At. Wt. of Ar=40)`

Explanation

To find the percentage of empty space in solid argon, we can follow these steps:

### Step 1: Calculate the volume of one argon atom
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 argon atom. Given \( r = 1.54 \times 10^{-8} \) cm, we can substitute this value into the formula.
