Question

Nickel is a metal that forms a face centered cubic lattice. It has a density of 8.908 g/cm³ and a molar mass of 58.7 g/mol. Show your units for all answers.

a. What is the volume in cubic centimeters of a single unit cell of nickel?

b. What is the radius of a nickel atom in pm?

c. If you tried to find the d spacing of a unit cell of nickel using x-rays with a wavelength of 154 pm, what would the observed theta value of the 2^nd order diffraction beam be in degrees?
