Volume occupied by hydrogen gas at 2 atm and 273 .^(@)C which contain 2 gm atoms of hydrogen is -

Answer»

`11.2` litre
`44.8` litre
2 litre
`22.4` litre

Solution :`n_(H) = 2` (GIVEN)
`n_(H_(2)) = (n_(H))/(2) = (2)/(2) = 1`
`PV = nRT` for `H_(2)` GAS
`2 xx V_(H_(2)) = 1 xx 0.0821 xx 546`
`2 xx V_(H_(2)) = 2 xx 22.4`
`V_(H_(2)) = 22.4` litre
