Answer:

1.5 mol.

Explanation:

  • From the balanced equation: Mg + 2HCl → MgCl₂ + H₂,

It is clear that 1.0 mol of Mg reacts with 2.0 moles of HCl to produce 1.0 mol of  MgCl₂ and 1.0 mol of H₂.

Using cross multiplication:

2.0 moles of HCl → 1.0 mole of MgCl₂.

3.0 moles of HCl → ??? mole of MgCl₂.

∴  The no. of moles of MgCl₂ are produced from 3.0 moles of HCl = (3.0 mol)(1.0 mol) / (2.0 mol) = 1.5 mol.
