    Answer:

    1.25 moles of magnesium chloride are produced

    Explanation:

    Based on the reaction:

    Mg(s) + 2HCl (aq) → MgCl₂(s) + H₂(g)

    1 mole of magnesium, Mg, reacts with 2 moles of hydrochloric acid, HCl, to produce 1 mole of magnesium chloride, MgCl₂ and 1 mole of hydrogen gas.

    To solve this question we have to tak, from the chemical equation:

    2 mol HCl = 1mol MgCl₂

    That means, the moles of MgCl₂ produced from 2.50mol HCl are:

    2.50 mol HCl * (1mol MgCl₂ / 2mol HCl) =

    1.25 moles of magnesium chloride are produced
