Ahypothetical element has an atomic weight of 230.300 amu and a density of 10480 kg/m3. assume the solid forms the fcc crystal structure and determine: the atomic radius in nano-meters the linear atomic density in atoms / n-m for the [110] direction. what is the planar atomic density in atoms / (n-m)2 for the (111) plane.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
