Question

Assuming $O_2$ molecule spherical in shape and occupying the radius 150 pm,
The volume of single molecule of gas is $1.41\times {10}^{-x}c{m}^3$
value of x is........

Answer 1

As we know,
volume of sphere is $4/3\pi r^3$
So, volume of $O_2$ molecule is $4/3\ast 3.14\ast (150\ast ({10}^{-10}{)}^3=1.41\ast {10}^{-23}$
So, value of x is 23.
