    3.2 moles

    Explanation:

    The equation for the reaction between copper and sliver nitrate is given by;

    Cu + AgNO₃ → Ag + CuNO₃

    This is a single replacement reaction in which copper which is more reactive than silver displaces silver from its salt.

    We are given;

    Moles of copper, Cu as 3.2 moles

    We are required to calculate the moles of silver metal formed.

    We need to first determine the mole ratio of Cu to Ag

    From the equation 1 mole reacts to form 1 mole of silver metal Therefore, mole ratio of Cu to Ag is 1 : 1 Thus, moles of Cu = Moles of Ag

    Hence,

    The number of moles of Ag formed is 3.2 moles
