1. Listed below are the atomic weight, density, and atomic
radius for three hypothetical alloys. For each determine its
crystal structure and then justify your determination.
Alloy // Atomic weight (g/mol) // Density (g/ cm^3) //
Atomic Radius (nm)
A // 43.1 //
6.4 // 0.122
B // 184.4 // 12.3
// 0.146
C // 91.6 // 9.6
// 0.137
The atomic weights of Al28, Fe56 and Cd112 (those are Aluminum,
Iron and Cadmium) are 27.982, 55.935 and 111.903 atomic mass units
(amu), respectively. Imagine fusing two of these Al nuclei to form
one Fe nucleus. Then, imagine fusing two of these Fe nuclei to make
one Cd nucleus.
a) What are the mass differences between the input nuclei and
the output nucleus in the two cases described? Provide your answer
in amu and g. Be consistent about signs!
