`2xx10^(8)` 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» Total length `=3.0 cm` Total number of atoms along the length `=2xx10^(8)` :. Diameter of each atom `=(3.0 cm)/(2xx10^(8))=1.5xx10^(-8) cm` :. Radius of the atom`=(1.5xx10^(-8)cm)/2=0.75xx10^(-8) cm` `=0.075xx10^(-7) cm` `0.075 10^(-9) m` `=0.075 nm` |
