how many moles of HCl are needed to react with 2.3 moles of Zn in the following reaction? 2HCl + Zn --> ZnCl2 + H2

Zn + 2HCl ==> ZnCl2 + H2

The equation tells you that 1 mole Zn reacts with 2 moles HCl. So 2 moles Zn will react with 4 moles HCl and 3 moles Zn will react with 6 moles HCl. Get the picture?
