Question

Radius of a spherical molecule of a gas is $2\times {10}^{-8}cm$. Volume per molecule is $3.35\times {10}^{-x}c{m}^3$
value of x is_______.

Answer 1

Radius of a spherical molecule of a gas is $2\times {10}^{-8}cm$.
volume per molecule is $3.35\times {10}^{-x}c{m}^3$
value of x is 23.
The volume of spherical molecule is $\frac{4}{3}\pi r^3=\frac{4}{3}\times 3.1416\times (2\times {10}^{-8}{)}^3=3.35\times {10}^{-23}$
