ANSWER:
Step 1 of 5
Here, we are going to find out the difference between the occupancy of a given volume of potassium and actual volume of potassium.
First, we calculate the radius of potassium in cubic centimeters.
From the figure atomic radius of the potassium is 227pm.
Conversion factor.
= 227pm
= .
