    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.
