2 × 108 atoms of carbon are arranged side by side. Calculate the radius of carbon atom if the length of this arrangement is 2.4 cm.

Question 2.36: 2 × 10⁸ atoms of carbon are arranged side by side. Calculate the radius of carbon atom if the length of this arrangement is 2.4 cm.
Answer
Length of the given arrangement = 2.4 cm
Number of carbon atoms present = 2 × 10 ⁸
∴ Diameter of carbon atom
