Hey, if all hope is lost try this...let me know if it makes sense....
use stoicheometry.
(287 amu of Li/ 1 )*( 1 mol/ 6.02 x 10^23) * ( 6.94g Li/ 1 mol)
this makes more clearer as fractions on paper....hope this helps. i did this and got 3.31 x 10^-21. (numbers may vary slightly with decimals cuz of periodic tables and diff. masses.)
