a 0.0194 g sample of copper metal is recycled through the series of reactions in an experiment. If 0.0169 g of copper is then recovered after the series of reactions in this experiment, what is the percent recovery of the copper metal?
Homework Answers
percent recovery = recovered mass / sample mass
= (0.0169 / 0.0194 ) x 100
= 87.11 %
percent recovery of the copper metal = 87.11 %

A student dissolved 0.44g of copper wire and followed all steps described in the copper cycle experiment to obtain solid copper. After performing the series of reactions a student weighed a total mass of 24.61g on the scale. This mass included the filter paper mass of 0.23g and the watch glass of 24.19g. Calculate the % recovery for this experiment. %recovery= final mass of copper grams divided by initial mass of copper grams
