Question

How many moles of Copper are needed to react with 8.5 moles of Silver I Nitrate?
Use the equation: Cu + AgNO3 → Cu(NO3)2 + Ag?

Answer 1

The balanced chemical equation is:

Cu + 2AgNO3 → Cu(NO3)2 + 2Ag

So, 1 part of copper reacts with 2 parts of silver nitrate.

As 8.5 moles of AgNO3 are required to completely react.

So, 2 pats is 8.5 moles.

Hence, 1 part is 8.5/2 => 4.25 moles.

Hence, 1 part of copper or 4.25 moles of Cu are needed in this reaction.
