# 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. - Chemistry

Numerical

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.

#### Solution

Length of the given arrangement = 2.4 cm

Number of carbon atoms present = 2 × 108

∴ Diameter of carbon atom

= (2.4xx10^(-2)" m")/(2xx10^8)

= 1.2 xx 10^(-10) " m"

:. "Radius of carbon atom"  = "Diameter"/2

= (1.2 xx 10^(-10)" m")/2

= 6.0 xx 10^(-11) " m"
