molecular mass of gas = 2*V.D.

                                 =2*11.2 =22.4

no of moles of gas = weight/ molecular mass

                            = 1/22.4

vol oF gas = no of moles * V

                = 1/ 22.4 * 22.4

                = 1 L

SINCE VAPOUR DENSITY OF A GAS  * 2 =MOLECULAR WEIGHT OF THA GAS 
M.WT.=2*V.D 
          = 2*11.2
          = 22.4g
therefore 22.4g 0f gas at ntp occupies 22.4 L volume 
then 1g oggas at ntp occupies 1L

The answer to your question is 1 litre.
This is because VD=2*Molecular mass
 
SINCE VAPOUR DENSITY OF A GAS  * 2 =MOLECULAR WEIGHT OF THA GAS 
M.WT.=2*V.D 
          = 2*11.2
          = 22.4g
therefore 22.4g 0f gas at ntp occupies 22.4 L volume 
then 1g oggas at ntp occupies 1L
