An experiment was conducted to bring the density of Cu from 9750 kg/m3 to 8770 kg/m3. They used the concept of making an alloy, where the foreign atom selected can substitute for Cu in fcc structure. If they used Sn atoms, what is the at% of Sn in Cu-Sn alloy? (Atomic mass of Cu=63.54 g/mol and Sn=118.69 g/mol)
