Question

2 x 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 1

Total Length = 2.4 cm

Total number of atoms along the length = 2 × 108

Therefore diameter of each atom = 2.4 / (2 × 108)

= 1.2 x 10-8 cm

And radius of the atom = (1.2 x 10-8) / 2

= 0.60 x 10-8cm

= 0.060 x 10-9m

= 0.060nm

Answer 2

Answer:

radius would be 0.6*10^-8cm

Explanation:

hey!! buddy

        given that: no.of carbon atoms= 2*10^8

                       length= 2.4cm

let the radius   be r.  

    then; 2*10^8 *2r (d)= 2.4cm

r = 0.6*10^-8cm

  or

0.6*10^-10m

        hope it helps...
