The mass of zinc required to obtain 2 mol of hydrogen according to the following transformation scheme is Zn + 2HCl → ZnCl2 + H2 ↑.
Zn + 2HCl → ZnCl2 + H2 ↑ – the reaction equation shows that one mole of zinc reacts with two moles of hydrochloric acid, forming one mole of zinc chloride and one mole of hydrogen. To possess two moles of hydrogen, we need to take twice as many substances, which means that there will be two moles of zinc. The mass of two moles of zinc is 130 grams. Thus, the mass of zinc required to obtain 2 mol of hydrogen according to the transformation scheme is 130 grams.
