The edge of a body-centered-cubic unit cell (which contains two atoms per unit cell) of an element Y was found to be #3.16 x 10^-8# cm. The density of the metal is #19.35##g/(cm^3)#. What is the approximate molar mass of Y?
The approximate molar mass of
Step 1. Calculate the volume of the unit cell
Step 2. Calculate the mass of a unit cell
Step 3. Calculate the mass of one atom
This is the mass of two atoms.
The approximate molar mass of the element is 184 g/mol.
