Q.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.
Total length = 2.4 cm
Total number of atoms along the length = 2×108
∴ Diameter of each atom = 2.4 cm/2×108 = 1.2×10-8 cm
∴ Radius of the atom = Diameter/2 = 1.2×10-8 cm/2 = 0.6×10-8 cm
