Atomic radii of fluorine and neon in Angstrom units are respectively given by

Options

A. `1g` of `O_(2)`,`2g` of `SO_(2)`
B. `1g` of `CO_(2)` , `1g` of `N_(2)O`
C. `112ml` of `O_(2)` at `STP,` `224 ml` of `He` at `0.5atm` and `273K`
D. All of these

Answer

4

Explanation

`(1)` No. of molecules of `O_(2)=(1)/(32)N_(a)`
No. of molecules of `SO_(2)=(2)/(64)Na` or `(1)/(32)N_(a)`
`(2)` No. of molecules of `CO_(2)=(1)/(44)N_(a)`
No. of molecules of `N_(2)O=(1)/(44)N_(a)`
`(3)` No. of molecules of `O_(2)` at `STP=(112)/(22400)=0.0050`
No. of molecules of `He=(PV)/(RT)=((224)/(1000)xx0.5)/((1)/(2)xx273)=0.0050`
