In comparing the density of bronze composed of 20% tin (r = 140 pm,7.37 g/cm 3 )to the density of pure copper (r = 128 pm,8.92 g/cm 3 ),________

The density of bronze is lower because tin has a lower density than copper, and adding tin to copper reduces the overall density.

Multiple Choice

In comparing the density of bronze composed of 20% tin (r = 140 pm,7.37 g/cm³) to the density of pure copper (r = 128 pm,8.92 g/cm³) ,________

A) the density of the bronze is lower.
B) the density of the bronze is higher.
C) the density of the bronze is the same.
D) the density of the bronze depends on whether the tin or the copper occupies holes.
