Question:

α-Mn has a cubic structure with a0 = 0.8931 nm and a density of 7.47 g/cm3. β-Mn has a different cubic structure with a0 = 0.6326 nm and a density of 7.26 g/cm3. The atomic weight of manganese is 54.938 g/mol and the atomic radius is 0.112 nm. Determine the percent volume change that would occur if α-Mn transforms to β-Mn.
