Silver metal is expensive and should always be recycled. If your lab has 0.500 L of silver nitrate solution (2 .00 mol* L^ -1 ) what mass of copper should you add to extract all the silver metal by single displacement ? Cu(s)+2 AgNO 3 (aq) Cu(NO 3 ) 2 (aq)+2 Ag(s)

Mass of Copper : 63.5 g

Given

Reaction

Cu(s)+2AgNO₃ (aq) ⇒Cu(NO₃)₂ (aq)+2Ag(s)

Required

Mass of Copper

Solution

mol of Silver nitrate :

= M x V

= 2 mol/L x 0.5 L

= 1

From the equation, mol ratio of Cu : AgNO₃ = 1 : 2, so mol Cu = 1

Mass of Cu(Ar=63.5 g/mol) :

= mol x Ar

= 1 x 63.5

= 63.5 g

output?

explanation:

the answer is 75.0%.
