Question

In the reaction, Cu + 2AgNO3 --> Cu(NO3)2 + 2Ag, 12.7 g Cu produced 38.1 Ag. Which one is percent yield of silver? a) 29.4% b)56.7% c)77.3% d)88.2% e)176%

Answer 1

In questions like this, always convert to moles. How many moles of Cu and Ag are there?

Answer 2

you need to use the 12.7g of Cu as your starting point and find out how many grams of silver \(should \space have \space been\) produced, then compare that to the amount that is \(actually\) produced to find your percent yield
