    The balance chemical equation is as follow,

    Cu + 2 AgNO₃ → Cu (NO₃) ₂ + 2 Ag

    First calculate for 200 g of AgNO₃,

    According to equation,

    339.74 g (2 mole) AgNO₃ produced = 215.7 g (2 mole) of Ag

    So,

    200 g of AgNO₃ will produce = X g of Ag

    Solving for X,

    X = (200 g * 215.7 g) : 339.74 g

    X = 126.97 g Ag

    Next calculate for 100 g of Cu,

    According to equation,

    63.52 g (1 mole) Cu produced = 215.7 g (2 mole) of Ag

    So,

    100 g of Cu will produce = X g of Ag

    Solving for X,

    X = (100 g * 215.7 g) : 63.52 g

    X = 339.57 g Ag

    Result:

    As 200 g of AgNO₃ is producing Ag in less amount (126.97 g) as compared to 100 g of Cu, it means that AgNO₃ is in limited amount and will consume first till the production of 126.97 g of Ag. So, the maximum amount of Ag production is 126.97 g.
