0.340.34 litres of hydrogen gas is produced.

Explanation:

The suggested reaction is rarr

Zn+2HClrarrZnCl_2+H_2(g)Zn+2HClZnCl2+H2(g)

Now, gram atomic mass of Zinc is 65.38g65.38g.

So from the equation,

65.38g65.38g of ZnZn produces 2g2g of H_2H2.

:.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:)
