Assume that you performed the experiment from lab this week and found that the mass of 10 pennies was equal to 25.024 g and displaced a volume of 3.42 mL. If pennies are composed of copper (density 8.96 g x cm) and zinc (density = 7.13 g x cm) only, what is the percent composition of the pennies in copper by density?
