What mass of copper is required to replace silver from 4.00g of silver nitrate dissolved in water? i found the molar mass of all of them but don't know where to go from there

0.7479 grams of copper is required to replace 4.00 grams of silver nitrate.

Explanation:

Moles of silver nitrate =

According to reaction 2 moles of silver nitrate reacts with 1 mole of copper metal.

Then 0.02354 moles of silver nitrate will react with:

Mass of 0.01177 moles copper =0.01177 mol × 63.55 g/mol = 0.7479 g

0.7479 grams of copper is required to replace 4.00 grams of silver nitrate.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
