When copper wire is placed into a silver nitrate solution, silver crystals and copper(II) nitrate solution form. If 57.1 g silver is actually recovered from the reaction, determine the percent yield of the reaction.

Answer 1

2AgNO3 + Cu ==>Cu(NO3)2 + 2Ag

Here is an example of a stoichiometry problem (solved). Just follow the steps. You can calculate the theoretical yield in that manner, then %yield = 57.1 g Ag/theoretical yield)*100 = ??
