#0.34# litres of hydrogen gas is produced.

The suggested reaction is #rarr#

#Zn+2HClrarrZnCl_2+H_2(g)#

Now, gram atomic mass of Zinc is #65.38g#.

So from the equation,

#65.38g# of #Zn# produces #2g# of #H_2#.

#:.1g# of #Zn# produces #2/65.38g# of #H_2#.

Now, #1# mole or #2g# of #H_2# gas occupies a volume of #22.4L#.

#:.2/65.38g# of #H_2# gas occupies #rarr#

#=22.4/2xx2/65.38L#.

#=0.34L#. (Answer).

Hope it Helps:)
