Technician A says to make sure all vehicle protection is removed prior to releasing the vehicle to the customer. Technician B says that prior to customer pick up of the repaired vehicle you should ensure that no damage to the vehicle has been sustained during repair. Who is correct?

A-mn has a cubic structure with a0 0.8931 nm and a density of 7.47 g/cm3. b-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 a-mn transforms to b-mn.
