Question
What is the density of KCl at 25.00 °C if the edge length of its fcc unit cell is 628 pm?

The internet lists density of KCl as 1.98 g/cc.
nass single molecule = molar mass/6.022E23 = ?
There are 4 molecules to the unit cell; therefore, mass unit cell is 4*mass single molecule.
Colume = (edge length)^3
Finally, density = mass unit cell/volume unit cell = ?
