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
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 24.66g on the scale. This mass included the filter paper mass of 0.23g and the watch glass of 24.25g. Calculate the % recovery for this experiment.
Mass of copper wire: 0.2605 Mass of filter paper. 0.5233 g Mass of filter paper + CuQ: 08319 g Mass of filter paper. 0.5005 g Mass of filter paper + Cu: 0.7300 g Calculate the following: o Mass of CuQ (Experimental Yield): Mass of CuO that could be produced from Cu wire (theoretical yield) % yield Cuo. SY For the next part, the theoretical yield is just your mass of % yield = experimental Yield a X 100 Theoretical Yield...
Question 18 Needs Grading In the "Chemical Reactions of Copper and Percent Yield" experiment, you carried out a series of chemical transformations involving copper. If you started out with 0.280 g of copper, and at the end of the reactions obtained 0.185 g of copper, what is your percent yield?
In an experiment a student dissolves a 5.14g copper wire nitric acid. After completing the steps in this experiment, the student collects 6.65g of dry copper. Calculate the % recovery of copper. List 2 possible experimental errors that would cause a recovery greater than 100%
