What is the percent abundance (in units of percent) of zinc in a sample whose density is 8.8g/mL and the only other component is copper? The density for pure copper is 8.96 g/cm3 and the density of pure zinc is 7.13g/cm3. Report your answer to one decimal place. NOTE: This question is meant to give you practice before your data. The density value generated is random within a certain realistic constraint. It will not be representative of your data in the experiment
