One mole of an ideal gas at standard temperature and pressure occupies 22.4 L (molar volume). What is the ratio of molar volume to the atomic volume of a mole of hydrogen? (Take the size of hydrogen molecule to be about 1 $ \dot{A}$ ). Why is this ratio so large?

$\begin {array} {1 1} (A)\;7.08 \times 10^5 & \quad (B)\;7.08 \times 10^6 \\ (C)\;7.08 \times 10^8 & \quad (D)\;7.08 \times 10^4 \end {array}$
