Calculate the volume occupied at `270^(@)C and 2` atm pressure of the gas evolved by 2 mL of solid `CO_(2)`. Given density of solid `CO_(2)` is `1.53 g mL^(-1)`

Explanation

Given, P(723/760) atm, w=3.2 g,
T=273+450=723 K, V=(780/1000) litre
`because PV =(w)/(m) RT`
`therefore m=(wRT)/(PV)`
`=(3.2xx0.0821xx760xx1000xx723)/(723xx780)=256`
`because 32 g" S has N atom of S"`
`therefore 256 g` S has (256/32) N atoms of S=8 N atoms of S=8 N atoms of S
`therefore` molecular formula of `S=S_(8)`
