I think that you will find that there are therefore two complete Li atoms per unit cell - look at the diagram to make sure.

So the mass is 2 x Ar/Avodadro's number.

Now you can work it out!

you make it sample and do it this way since it is cubic unit cell
cubic is 2 to 2
2 times 6.94g over (6.02*10^23) = 2.30*10^-23

"Ar"= mass of Lithium

(6.94^2)/(6.02 x10^23)=2.30 x 10^-23
