what are the number of grams of Li3N?
Your question doesn't make sense...
but 1 mol of a compound has the mass equal to the sum of the relative mass of each atom present in the compound.
In other words, find the molecular mass of Li3N.
Then, 1 mol of this has this mass in grams.
If you're looking for some number 'x' moles, then
x moles of Li3N will have a mass x times the mass of 1 mol.
