Rearrange the following (I to IV) in the order of increasing masses:
(I) `0.5 "mole o f" O_(3)`
(II) 0.5 gm atmo of oxygen
(III) `3.011xx 10^(23) " molecules of " O_(2)`
` 5.6" litre of " CO_(2) " at 1 atm and 273 K "`

Options

A. `II lt IV ltIII lt I`
B. `II lt Ilt IV ltIII`
C. `IV lt II lt III lt I`
D. `I lt II lt III lt IV`

Answer

A

Explanation

`(I)" "0.5 mol e O_(3)=24gO_(3), " "(II)" "0.5g` at om of oxygen`=8g`
`(III)" "(3.011xx10^(23))/(6.022xx10^(23))xx32=16gO_(2)," "(IV)" "(5.6)/(22.4)xx44gCO_(2)=11gCO_(3)`
