Answer #2
The density of Cu is 8.96 g/cm^3. The density of Pb is 11.4 g/cm^3. Let the mass fraction of copper, Cu = x, Then the mass fraction of Pb is (1-x). The algebraic expression for the "weighted" average density is:
8.96x + 11.4(1-x) = 9.60
Solve for x to get the mass fraction for copper. How would you get the mass fraction of Pb?
