If 1.0g Zn is dropped in a solution of concentrated HCl, how many moles of hydrogen gas is produced?
Zn (s) + 2 HCl (aq) ---> H2 (g) + ZnCl2 (aq).
If possible, please provide the solution. Thank you!

No of moles of Zn: [Molar mass = 65.4 g.mol-1]
No of moles = Mass/molar mass = 1/65.4 = 0.0153 mol
1 mol Zn produces 1 mol H2
So 0.0153 mol Zn produce 0.0153 mol H2 ==> Answer
