The volume occupied by an atom is greater than the volume of the nucleus by a factor of about

A

10110^1

B

10510^5

C

101010^{10}

D

101510^{15}

Answer

101510^{15}

Explanation

Solution

Volume of atomVolume of nucleus\frac {Volume\ of \ atom}{Volume\ of\ nucleus}

= 43π(10−10)343π(10−15)3\frac {\frac 43 \pi (10^{-10})^3 }{\frac 43 \pi (10^{-15})^3}

= 10−3010−45\frac {10^{-30}}{10^{-45}}

= 101510^{15}

So, the correct option is (D): 101510^{15}
