Question 8 (1 point) Vanadium (50.9 g/mol) is a metal that under normal conditions crystallizes in a body- centered cubic lattice and has a density -6 g/cm3. If instead vanadium were to crystallize in a simple cubic lattice, calculate the new density. The atomic radius of vanadium is 205 pm. HINT: First, calculate the edge length of a simple cubic cell from the atomic radius (1 suggest converting to cm at this step). Second, calculate the volume of the unit...

The toxic, highly unstable element derium (chemical symbol De) is discovered and is found to have a body-centered cubic unit cell. The radius of a derium atom is 86.906pm and the density of solid derium is 133.8g/cm3 at 25.0°C. a) Calculate the length (in pm) of an edge of the bcc unit cell for derium. 1) b) Calculate the molar mass (in g/mol) of derium. c) As for any cubic unit cell, part of the derium unit cell is empty...
Unit Cell Calculations Name _____________________________ Unit Cells: The Simplest Repeating Unit in a Crystal The structure of solids can be described as if they were three-dimensional analogs of a piece of wallpaper. Wallpaper has a regular repeating design that extends from one edge to the other. Crystals have a similar repeating design, but in this case the design extends in three dimensions from one edge of the solid to the other. We can unambiguously describe a piece of wallpaper by...
