How many moles of hydrogen are produced from the reaction of three moles of zinc with an excess of hydrochloric acid in $Z n + 2 H C l \to Z n C l_{2} + H_{2}$ $Zn + 2HCl -> ZnCl_2 + H_2$ ?

3 moles

as per given balanced equation one mole Zn produces 1mole Hydrogen
when reacted with excess acid.
So 3 moles Zn will give 3moles Hydrogen

How many moles of hydrogen are produced from the reaction of three moles of zinc with an excess of hydrochloric acid in Zn+2HCl→ZnCl2+H2Zn + 2HCl -> ZnCl_2 + H_2?
