In which one of the following, does the given amount of chlorine exert the least pressure in a vessel of capacity 1" cm"^(3) at 273 K ?

Answer»

`0.0355` g
`0.071 g`
`6.023xx10^(21)` molecules
`0.02` MOLE

SOLUTION :`Ppropn` (no. of moles)
Molecular weight of chlorine `=71` g
`0.0355g=5xx10^(-4)` moles
`0.071g=1xx10^(-3)` moles
`6.023xx10^(21)` molecules `=0.01` moles `0.02` moles `=0.02` moles
