If 2.50 mol of copper and 5.50 mol of silver nitrate are available to react by a single replacement:Cu + 2AgNO3 -> Cu(NO3)2 + 2Ag

What is the amount in moles of each product formed?

1 answer

Anytime BOTH of the reactants are listed the problem is a limiting reagent one.
Convert moles Cu to moles of the products.
Convert 5.5 moles AgNO3 to moles of the products.
The reagent producing the smaller number of moles of the products is the limiting reagent and the smaller number of moles will be the moles of the products after the reaction is complete.
