Answer» `7.1xx10^(4)` `7.1xx10^(6)` `7.1xx10^(10)` `7.1xx10^(8)` Solution :VOLUME occupied by 1 mole of an ideal gas at STP is KNOWN as molar volume. `THEREFORE` Molar volume `=22.4`litre `=22.4xx10^(-3)m^(3)` Radius of hydrogen atom is `r=0.5`Ã… `=0.5xx10^(-10)m` `therefore`Atomic volume `=(4)/(3)PIR^(3)N_(A)` `=(4)/(3)xx(22)/(7)xx(0.5xx10^(-10))^(3)xx6.023xx10^(23)` `=3.15xx10^(-7)m^(3)` their corresponding ratio is `("Molar volume")/("Atomic volume")=(22.4xx10^(-3)m^(3))/(3.15xx10^(-7)m^(3))=7.1xx10^(4)`
